MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted
Arina Puzriakova (Genomics England Curator)
Comment on list classification: New gene added by Tom Cullup (GOSH). There is sufficient evidence to promote this gene to green at the next GMS panel update. At least 17 cases have been identified with somatic mosaic variants in PIK3R1 (PMIDs: 34040190; 35964931). Affected individuals exhibit various vascular lesions and overgrowth which were comparable to features of the PIK3CA-related overgrowth spectrum.Created: 9 Aug 2023, 9:34 a.m. | Last Modified: 9 Aug 2023, 9:34 a.m.
