Oculofaciocardiodental syndrome

Oculofaciocardiodental (OFCD) syndrome, also known as microphthalmia syndromic type 2, is a rare X-linked dominant genetic disorder caused by mutations in the BCOR gene located on chromosome Xp11.4. The condition is characterized by a distinctive combination of abnormalities affecting the eyes, face, heart, and teeth. OFCD syndrome occurs almost exclusively in females, as it is presumed to be lethal in males during prenatal development. The key clinical features involve multiple body systems. Ocular findings include congenital cataracts and microphthalmia (abnormally small eyes), which may be unilateral or bilateral. Facial features can include a long narrow face, high nasal bridge, and cleft palate or bifid uvula. Cardiac defects are common and may include atrial or ventricular septal defects, mitral valve prolapse, and other congenital heart malformations. Dental abnormalities are particularly characteristic and include radiculomegaly (abnormally long tooth roots), delayed dentition, oligodontia (missing teeth), persistent primary teeth, and canine radiculomegaly, which is considered a hallmark feature. Additional findings may include toe syndactyly, hammer toes, and mild intellectual disability in some cases. There is no cure for OFCD syndrome, and management is multidisciplinary and symptom-based. Treatment typically involves ophthalmologic interventions such as cataract surgery, cardiac surgery for significant heart defects, orthodontic and dental management for the dental anomalies, and developmental support when needed. Regular monitoring by a team including ophthalmologists, cardiologists, dentists, and clinical geneticists is recommended to address the various manifestations of the condition throughout life.
