Women's Health and Genetics/Laboratory Corporation of America, LabCorp RCV001078269 SCV001360658 likely pathogenic beta Thalassemia 2019-08-07 criteria provided, single submitter clinical testing Variant summary: HBB c.316-1G>T is located in a canonical splice-site and is predicted to affect mRNA splicing resulting in a significantly altered protein due to either exon skipping, shortening, or inclusion of intronic material. 5/5 computational tools predict that the variant significantly impacts normal splicing by abolishing a 3' acceptor site. However, these predictions have yet to be confirmed by functional studies. The variant was absent in 251150 control chromosomes (gnomAD). c.316-1G>T has been reported in the literature in individuals affected with Beta Thalassemia (Najmabadi_2002). These data indicate that the variant may be associated with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. One clinical diagnostic laboratory has submitted a clinical-significance assessment for this variant to ClinVar (after 2014) and classified the variant as pathogenic. Based on the evidence outlined above, the variant was classified as likely pathogenic.
