Verheij syndrome is a rare genetic condition caused by changes in the PUF60 gene on chromosome 8, leading to a wide range of developmental and physical problems that typically appear early in life. Classified as an autosomal dominant disorder, it affects multiple body systems at once, with features spanning intellectual disability, heart defects, kidney abnormalities, skeletal differences, and distinctive facial characteristics. Because so few people have been identified with the condition worldwide, much of what clinicians know comes from detailed case reports and small case series rather than large-scale studies.
What Causes Verheij Syndrome
Verheij syndrome traces back to one of two related genetic events: either a deletion of a small stretch of DNA on the long arm of chromosome 8 (the 8q24.3 region) or a harmful change within a single gene in that region called PUF60.1PubMed Central. Novel PUF60 variant suggesting an interaction between Verheij and Cornelia de Lange syndrome: phenotype description and review of the literature In most reported cases the genetic change is “de novo,” meaning neither parent carries it. Instead, it arises spontaneously during the formation of the egg or sperm, or very early in embryonic development. That means families with no history of the syndrome can still have an affected child.
PUF60 encodes a protein involved in RNA splicing, the cellular editing process that takes raw genetic instructions and trims them into a usable format. When one copy of PUF60 is missing or broken, cells lose about half of the normal protein output. That shortfall disrupts the splicing of many downstream genes, which helps explain why the syndrome touches so many different organ systems at once.2PubMed.

Two Genes, One Syndrome
When the cause is a larger chromosomal deletion rather than a point change in PUF60 alone, a neighboring gene called SCRIB is typically lost as well. Research in zebrafish has helped tease apart what each gene contributes. Knocking down PUF60 alone produced heart defects, while knocking down SCRIB alone led to eye coloboma and kidney problems. Both knockdowns individually caused short stature, a small head, and a reduced jaw. When both genes were suppressed together, the growth problems became more severe.3PubMed Central.

For a while, this suggested that patients with large deletions (losing both PUF60 and SCRIB) might be more severely affected than those with a PUF60-only variant. But as more individuals with PUF60 point mutations have been identified, their features overlap heavily with those of deletion patients. That overlap points to PUF60 as the primary driver of most symptoms, with SCRIB adding to certain features like kidney and eye involvement.4PubMed Central. SCRIB and PUF60 are primary drivers of the multisystemic phenotypes of the 8q24.3 copy-number variant
Recognizing the Symptoms
Verheij syndrome affects many body systems, and no two patients look exactly alike. Still, a pattern emerges across published cases. The most comprehensive analysis to date, pooling data from 46 previously reported patients along with new cases, found the following approximate frequencies for core features:5PubMed. The diverse pleiotropic effects of spliceosomal protein PUF60: A case series of Verheij syndrome
- Neurodevelopmental delay or intellectual disability: nearly universal, reported in about 98% of cases.
- Skeletal differences: spinal anomalies in roughly three-quarters of cases, with limb and joint abnormalities at a similar rate.
- Oral anomalies: palate differences, feeding difficulties, or dental issues in about two-thirds.
- Short stature: present in roughly two-thirds of patients.
- Cardiac anomalies: reported in about 63% of cases, ranging from septal defects to more complex structural heart disease.
- Brain malformations: seen on imaging in close to half.
- Hearing loss: documented in just under half.
- Microcephaly: a smaller-than-expected head circumference, found in about 41%.
- Eye coloboma: a gap in the structure of the eye, seen in roughly 38%, with other ocular abnormalities bringing total eye involvement to about 65%.
A separate case series of ten additional patients reported somewhat different rates for some features, with skeletal abnormalities at around 80%, ocular abnormalities at 70%, and cardiac anomalies at 40%.6PubMed. PUF60-related developmental disorder: A case series and phenotypic analysis of 10 additional patients with monoallelic PUF60 variants The variation in reported frequencies is expected given the very small numbers involved. The overall message, though, is consistent: skeletal, eye, heart, and kidney problems cluster alongside developmental delays and growth restriction.
Feeding problems are worth highlighting because they often appear first. Infants with Verheij syndrome may have difficulty latching, swallowing, or gaining weight in the earliest weeks and months. Joint laxity, where joints are unusually loose and flexible, also shows up early and can compound motor difficulties.7PubMed Central. Clinical and Genetic Aspects of Verheij Syndrome in Two Cases
Developmental and Cognitive Effects
Developmental delay is the most consistent hallmark. Delays in communication, motor skills, and overall cognitive function have been reported in about 90% of reviewed cases.8European Journal of Human Genetics. Novel PUF60 variant suggesting an interaction between Verheij and Cornelia de Lange syndrome: phenotype description and review of the literature The degree of delay varies widely. Some children achieve speech and independent mobility with therapy, while others require substantial long-term support.
At least one published case described a child whose mild psychomotor and speech delays improved after physiotherapy and speech therapy, suggesting that early intervention can make a real difference in functional outcomes even when the underlying genetic cause cannot be corrected.8European Journal of Human Genetics. Novel PUF60 variant suggesting an interaction between Verheij and Cornelia de Lange syndrome: phenotype description and review of the literature Brain malformations visible on MRI are found in about half of patients, and these may correlate with more pronounced cognitive difficulties, though the case numbers are too small to draw firm statistical conclusions.
Kidney Involvement
Kidney abnormalities are one of the defining features of the syndrome, yet they range from severe to surprisingly mild. Reported kidney findings include a missing kidney on one side, a pelvic kidney (positioned lower than usual), horseshoe kidney, an undersized kidney, and hydronephrosis (swelling due to urine backing up). In at least one documented case, mild kidney findings detected in early childhood appeared to normalize during development.8European Journal of Human Genetics. Novel PUF60 variant suggesting an interaction between Verheij and Cornelia de Lange syndrome: phenotype description and review of the literature That variability makes ongoing monitoring important, even when initial imaging looks reassuring. Periodic ultrasound and kidney function testing are generally recommended for affected children.
How Verheij Syndrome Is Diagnosed
Because the features of Verheij syndrome overlap with several other conditions, a genetic test is the only way to confirm the diagnosis. The clinical picture, such as a combination of short stature, heart defects, eye coloboma, and developmental delay, may raise suspicion, but that constellation of problems can also point to CHARGE syndrome, Cornelia de Lange syndrome, or other rare multisystem disorders.
The diagnostic path typically starts with a standard chromosome analysis and a chromosomal microarray to look for deletions or duplications. If those come back normal, exome sequencing (which reads the protein-coding parts of every gene) is the tool that usually catches PUF60 variants. In one reported prenatal diagnosis, ultrasound findings during pregnancy prompted trio-based exome sequencing of the fetus and both parents, which identified a de novo disease-causing change in PUF60 that neither parent carried.9PubMed Central. A Prenatal Diagnosis of Verheij Syndrome in Fetus Harboring a de novo PUF60 Variant Prenatal detection remains uncommon, however, because many of the syndrome’s characteristic features are not clearly visible on ultrasound until later in pregnancy, if at all.
The rarity of Verheij syndrome means that many clinical geneticists may see only one or two cases in a career. For families, this often translates into a frustrating diagnostic odyssey, sometimes lasting years, before the right genetic test is ordered. Awareness among pediatricians and early-childhood specialists is slowly improving as more case reports appear in the literature, but the syndrome is still under-recognized.
Conditions That Can Be Confused with Verheij Syndrome
CHARGE syndrome is probably the closest clinical mimic. Both conditions can present with coloboma, heart defects, growth restriction, and developmental delay. CHARGE is caused by changes in the CHD7 gene, and some research has found overlapping molecular biology between the two conditions.10Genetics in Medicine. Genetic analysis of CHARGE syndrome identifies overlapping molecular biology From a practical standpoint, the key differences are that CHARGE more commonly involves choanal atresia (blocked nasal passages) and characteristic ear abnormalities, while Verheij syndrome tends to include more prominent skeletal and joint findings.
Cornelia de Lange syndrome is another condition that shares features with Verheij, particularly growth restriction, limb differences, and intellectual disability. One published case described a patient whose PUF60 variant produced features suggestive of both syndromes, raising the possibility that PUF60 interacts with pathways relevant to Cornelia de Lange as well.1PubMed Central. Novel PUF60 variant suggesting an interaction between Verheij and Cornelia de Lange syndrome: phenotype description and review of the literature For clinicians and families alike, these overlaps reinforce the importance of genetic testing rather than relying on clinical criteria alone.
Treatment and Management
There is no cure for Verheij syndrome, and no therapy that targets the underlying PUF60 deficiency. Management is entirely supportive and symptom-driven, which means treatment looks different for every patient depending on which organ systems are affected.
For heart defects, standard pediatric cardiology care applies: echocardiography for monitoring, and surgery when structural defects warrant it. Kidney abnormalities are tracked with imaging and function tests, with nephrological input when needed. Skeletal problems may call for orthopedic evaluation, and some children benefit from bracing or surgical correction of spinal anomalies. Eye coloboma and other ocular differences are managed by a pediatric ophthalmologist, with corrective lenses, patching, or surgery depending on the severity and how much vision is affected.
On the developmental side, early intervention programs are critical. Speech therapy, occupational therapy, and physiotherapy form the backbone of support for most affected children. The published literature includes at least one case where targeted therapy led to meaningful improvement in speech and motor milestones, so there is real reason for families to pursue these services aggressively from early infancy.
Growth Hormone Therapy and Its Limitations
Short stature is one of the more visible features of the syndrome, and growth hormone therapy has been tried in at least one documented case. That patient’s growth hormone treatment was ultimately stopped after the child developed idiopathic intracranial hypertension, a condition involving dangerously elevated pressure inside the skull.11PubMed Central. A Case Report of Verheij Syndrome Idiopathic intracranial hypertension is a known rare side effect of growth hormone treatment in other genetic conditions as well, but its occurrence in this context serves as a reminder that even well-intentioned interventions can carry risks in patients with complex multisystem syndromes.
Whether growth hormone therapy is advisable for other Verheij syndrome patients remains an open question. There are not enough cases to draw conclusions about its safety or effectiveness in this specific population. Families and clinicians typically weigh the potential growth benefit against the individual child’s constellation of other medical issues, particularly brain findings, on a case-by-case basis.
Hearing and Communication
Hearing loss, reported in close to half of all documented cases, deserves special attention because it compounds the communication difficulties already imposed by intellectual disability and speech delay.5PubMed. The diverse pleiotropic effects of spliceosomal protein PUF60: A case series of Verheij syndrome The hearing loss can be sensorineural (originating in the inner ear or auditory nerve), conductive (related to structural differences in the middle ear), or mixed. Newborn hearing screening may catch severe cases early, but milder losses sometimes go undetected until speech milestones are notably delayed. Audiological evaluation should be part of the initial workup for any child diagnosed with or suspected of having Verheij syndrome, and repeated periodically afterward, since hearing can change over time.
When hearing loss is identified, amplification with hearing aids or, in severe cases, cochlear implantation can remove a barrier to language development. Combined with speech therapy, addressing hearing loss early can substantially improve a child’s ability to communicate and participate in educational settings.
Variability Between Patients
One of the more striking aspects of Verheij syndrome is how different two patients with the same gene involved can look. Some individuals have relatively mild intellectual disability, no heart defect, and only subtle facial differences. Others have severe structural problems requiring multiple surgeries in infancy. The specific location and type of the PUF60 mutation likely plays some role in determining severity, but with fewer than 50 well-characterized patients in the global literature, genotype-phenotype correlations remain rough at best.
There is also the question of whether patients with large 8q24.3 deletions (losing both PUF60 and SCRIB) are consistently more affected than those with PUF60-only variants. The zebrafish data suggested that losing both genes worsens growth problems, but in practice the clinical picture is noisy enough that deletion size alone does not predict outcomes reliably.12American Journal of Human Genetics. SCRIB and PUF60 Are Primary Drivers of the Multisystemic Phenotypes of the 8q24.3 Copy-Number Variant This variability can be confusing for families looking for a clear prognosis, and it underscores the value of individualized medical follow-up rather than a one-size-fits-all management plan.
The Family Experience
Raising a child with any rare disease carries psychological and social costs that extend well beyond the medical appointments. Parents of children with neurodevelopmental differences frequently report feelings of isolation and a sense that their peers with typically developing children do not fully understand their situation.13PubMed Central. Psychosocial Considerations for the Child with Rare Disease: A Review with Recommendations and Calls to Action Homes can feel medicalized, with therapy schedules, specialist visits, and adaptive equipment reshaping daily life.
For a condition as rare as Verheij syndrome, these challenges are amplified. There is no large patient community to turn to for peer support or practical advice. Most pediatricians will never have seen another case, which means parents often become the de facto experts on their child’s condition. Systematic reviews of families affected by rare diseases have found that caregivers experience higher psychological distress, lower quality of life, and greater caregiver burden compared to the general population, and that some of these effects appear to be intensified specifically by the rarity of the diagnosis.14Journal of Child and Family Studies. Living with a Rare Disease: Psychosocial Impacts for Parents and Family Members – a Systematic Review
Online communities and registries for rare genetic syndromes have begun to fill some of that gap. Connecting with even a handful of other families dealing with the same diagnosis can provide practical insights, from which specialists are most experienced with the syndrome to what developmental milestones have been realistic for other children. For families navigating Verheij syndrome, seeking out these networks, as well as psychological support services designed for rare-disease caregivers, is a step that can meaningfully improve daily life alongside the medical management itself.
