Cataract-intellectual disability-hypogonadism syndrome

Cataract-intellectual disability-hypogonadism syndrome, also known as Martsolf syndrome, is an extremely rare genetic disorder characterized by the triad of congenital or early-onset cataracts, intellectual disability, and hypogonadism. The condition affects multiple body systems including the eyes, central nervous system, and reproductive system. Patients typically present with bilateral cataracts that may be present at birth or develop in early childhood, varying degrees of intellectual disability (often mild to moderate), and hypogonadotropic or hypergonadotropic hypogonadism leading to delayed or incomplete puberty and potential infertility. Additional features may include short stature, microcephaly, and characteristic facial features such as a prominent nasal bridge and thin upper lip. Some patients may also exhibit skeletal anomalies and neurological findings. Martsolf syndrome shares clinical overlap with Warburg Micro syndrome, and both conditions have been linked to mutations in genes encoding RAB3GAP1, RAB3GAP2, RAB18, and TBC1D20, which are involved in intracellular vesicle trafficking. Martsolf syndrome is generally considered the milder end of the Warburg Micro syndrome spectrum. Inheritance follows an autosomal recessive pattern. There is currently no cure or disease-specific treatment for this condition. Management is supportive and multidisciplinary, involving ophthalmologic surgery for cataracts, hormone replacement therapy for hypogonadism, educational support and developmental interventions for intellectual disability, and regular monitoring of growth and development. Early intervention programs can help optimize developmental outcomes. Genetic counseling is recommended for affected families.
