RCV000493055 | SCV000583062 | likely pathogenic | not provided | 2017-05-24 | criteria provided, single submitter | clinical testing | Although the c.1069_1070delAG likely pathogenic variant in the COL1A2 gene has not been reported to our knowledge, this variant causes a shift in reading frame starting at codon serine (S) 357, changing it to an arginine (R), and creating a premature stop codon at position 2 of the new reading frame, denoted p.Ser357ArgfsX2. This likely pathogenic variant is expected to result in either an abnormal, truncated protein product or loss of protein from this allele through nonsense-mediated mRNA decay. Other frameshift variants in the COL1A2 gene have been reported in Human Gene Mutation Database in association with COL1A2-related disorders (Stenson et al., 2014), indicating that loss of function is a mechanism of disease for this gene. Furthermore, the c.1069_1070delAG variant has not been observed in large population cohorts (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). |
