Illumina Laboratory Services, Illumina RCV001270844 SCV001451614 pathogenic Congenital contractural arachnodactyly 2019-03-12 criteria provided, single submitter clinical testing The FBN2 c.3424T>C (p.Cys1142Arg) variant is a missense variant that has been reported in one individual affected with crumpled ears, arachnodactyly, and contractures (Callewaert et al. 2008). The variant was inherited from the individual's mother who had contractures and scoliosis. The variant was absent from 200 control chromosomes and is not found in the Genome Aggregation Database in a region of good sequencing coverage, so the variant is presumed to be rare. The Cys1142 residue is present in the 16th EGF-like domain, and another missense change at the same residue, p.Cys1142Phe, has been reported in an individual affected with congenital contractural arachnodactyly (Belleh et al. 2000). Based on the collective evidence and application of the ACMG criteria, the p.Cys1142Arg variant is classified as pathogenic for congenital contractural arachnodactyly.
