Excerpted from the GeneReview: Congenital Cataracts, Facial Dysmorphism, and Neuropathy
Congenital cataracts, facial dysmorphism, and neuropathy (CCFDN) is characterized by abnormalities of the eye (bilateral congenital cataracts, microcornea, microphthalmia, micropupils); mildly dysmorphic facial features apparent in late childhood; and a hypo/demyelinating, symmetric, distal peripheral neuropathy. The neuropathy is predominantly motor at the onset and results in delays in early motor development, progressing to severe disability by the third decade. Secondary scoliosis and foot deformities are common. Sensory neuropathy develops after age ten years. Most affected individuals have a mild non-progressive intellectual deficit and cerebellar involvement including ataxia, nystagmus, intention tremor, and dysmetria. All have short stature and subnormal weight. Adults have hypogonadotropic hypogonadism. Parainfectious rhabdomyolysis (profound muscle weakness, myoglobinuria, and excessively elevated serum concentration of creatine kinase usually following a viral infection) is a potentially life-threatening complication. To date all affected individuals and carriers identified have been from the Roma/Gypsy population.
