MMEP syndrome

Synonyms: MCOPS8 | Microcephaly-microphthalmia-ectrodactyly of lower limbs-prognathism syndrome | Syndromic microphthalmia type 8 | Viljoen-Smart syndrome

The MMEP syndrome is a congenital syndromic form of split-hand/foot malformation (SHFM; see this term). It is characterized by microcephaly microphthalmia ectrodactyly of the lower limbs and prognathism. Intellectual deficit has been reported. MMEP syndrome is considered to be a very rare condition although the exact prevalence remains unknown. The etiology is not completely understood. Disruption of the sorting nexin 3 gene (SNX3; 6q21) has been shown to play a causative role in MMEP although this was not confirmed in recent studies.
