ARUP Laboratories, Molecular Genetics and Genomics,ARUP Laboratories RCV001001278 SCV001158454 likely pathogenic not specified 2019-05-27 criteria provided, single submitter clinical testing The COL1A1 c.1715G>C; p.Gly572Ala variant, to our knowledge, has not been described in the medical literature or in gene-specific databases. It is also absent from general population databases (Exome Variant Server and Genome Aggregation Database), indicating it is not a common polymorphism. This variant disrupts the repeating Gly-X-Y sequence motif of the collagen triple helix and is predicted to impair collagen function (Ben Amor 2011). Additionally, several other surrounding glycine substitutions in this exon have been reported in individuals affected with osteogenesis imperfect types II and IV and are considered pathogenic (Marini 2007). Based on available information, the p.Gly572Ala variant is considered likely pathogenic. REFERENCES Ben Amor I et al. Genotype-phenotype correlations in autosomal dominant osteogenesis imperfecta.
