Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine RCV004018190 SCV004848721 likely pathogenic Glanzmann thrombasthenia 2022-06-30 criteria provided, single submitter clinical testing The c.189-1G>C variant in ITGA2B has not been previously reported in individuals with Glanzmann thrombasthenia and was absent from large population studies. This variant occurs within the canonical splice site (+/- 1,2) and is predicted to cause altered splicing leading to an abnormal or absent protein. Loss of function of the ITGA2B gene is an established disease mechanism in autosomal recessive Glanzmann thrombasthenia. In summary, although additional studies are required to fully establish its clinical significance, this variant meets criteria to be classified as likely pathogenic for autosomal recessive Glanzmann thrombasthenia. . ACMG/AMP criteria applied: PVS1, PM2_Supporting.
