RCV000780315 | SCV000917482 | pathogenic | Hemoglobinopathy | 2018-05-11 | criteria provided, single submitter | clinical testing | Variant summary: HBB c.93-2A>C 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. Several computational tools predict a significant impact on normal splicing: Five predict the variant abolishes a 3-prime acceptor site. However, these predictions have yet to be confirmed by functional studies. The variant was absent in 246058 control chromosomes. The variant, c.93-2A>C, has been reported in the literature in individuals affected with Beta Thalassemia Major (Old 2001, Fisher 2003, Agarwal 2010, Panja 2017), all of these cases were reported from the Indian Subcontinent. These data indicate that the variant is likely to 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 clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation, and classified the variant as pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic. |
