Congenital cataract facial dysmorphism neuropathy syndrome: a clinically recognizable entity

Congenital cataracts facial dysmorphism neuropathy syndrome is a recently delineated autosomal recessive condition exclusively found in the Gypsy population. Congenital cataracts facial dysmorphism neuropathy syndrome is caused by a homozygous mutation in the CTDP1 gene, leading to disruption of the ribonucleic acid transcription machinery. This report presents a young Gypsy female affected by this rare disorder. Electromyography and sural nerve histology were in accordance with a hypomyelinating neuropathy. After clinical recognition of congenital cataracts facial dysmorphism neuropathy syndrome some years ago, we recently demonstrated the presence of the homozygous IVS6+389C-->T mutation in the CTDP1 gene in this family.
