A novel KIF7 mutation in two affected siblings with acrocallosal syndrome

Clin Dysmorphol. 2015 Apr;24(2):61-4. doi: 10.1097/MCD.0000000000000080.

Abstract

Acrocallosal syndrome (ACLS) is a rare genetic disorder typically characterized by craniofacial dysmorphism, agenesis, or hypoplasia of the corpus callosum, and duplication of the phalanges of halluces and/or the thumbs. ACLS is a recessive ciliopathy caused by mutations in KIF7. We identified a Turkish family who had a novel homozygous sequence change, c.2593-2A>C, located at the acceptor splice site of intron 12 of KIF7 (IVS12-2A>C). The present report will contribute towards further understanding of the genotype-phenotype correlation in ACLS caused by KIF7 mutations.
