| Impact List | deletion |
| Protein Effect | loss of function |
| Gene Variant Descriptions | TSC2 H1746_R1751del (also referred to as R1743_K1748del) results in the deletion of six amino acids in the Rap-GAP domain of the Tsc2 protein from amino acids 1746 to 1751 (UniProt.org). H1746_R1751del confers a loss of function on the Tsc2 protein as indicated by destabilization of the TSC1-TSC2 complex (PMID: 21309039), increased phosphorylation of S6, potentially resulting in hyperactivation of Mtorc1, and a decrease in Akt phosphorylation in cultured cells. (PMID: 31591157). |
