Congenital cataracts, facial dysmorphism, and neuropathy (CCFDN) syndrome is a rare autosomal recessive, complex developmental disorder exclusively manifested in the Roma population. CCFDN is a genetically homogeneous condition in which all patients are homozygous for the same ancestral mutation in the CTDP1 gene. Affected patients display congenital cataracts, microcornea, peripheral neuropathy, mild facial dysmorphism, hypogonadism, and psychomotor delay.
