Abstract

We report four individuals from two unrelated consanguineous families with 3MC syndrome. In the first family, chromosome microarray data revealed that the two affected sisters, born to first-cousin parents, shared a unique homozygous C-terminal deletion in the COLEC11 gene. Two affected brothers from a second family, also born to first-cousin parents, shared a region of homozygosity that included the second gene known to cause the 3MC syndrome, MASP1. We discuss the diagnostic approach of craniofacial disorders born to consanguineous parents and highlight a literature search and reference a helpful dysmorphology solution powered by FDNA (Facial Dysmorphology Novel Analysis) technology.
