Abstract

The disorder comprising Macrocephaly, Alopecia, Cutis laxa, and Scoliosis has been designated MACS syndrome. It is a rare condition, inherited in an autosomal recessive pattern. Three families from different ethnic origins have so far been reported and were all linked to homozygous mutations in RIN2, a gene encoding the Ras and Rab interactor 2 protein involved in cell trafficking. We describe herein the fourth family with MACS syndrome in two siblings carrying a novel homozygous mutation, c.1878_1879insC in exon 8 of the RIN2 gene, which predicts p.Ile627Hisfs*7. We also report on additional findings not previously described in MACS syndrome, including bronchiectasis and hypergonadotropic hypogonadism. Finally, our overall data support the argument that RIN2 syndrome is a more appropriate name for the disorder. (c) 2013 Wiley Periodicals, Inc.
