| Protein Effect | loss of function |
| Gene Variant Descriptions | TSC2 N1643H lies within the Rap-GAP domain of the Tsc2 protein (UniProt.org). N1643H demonstrates protein stability similar to wild-type Tsc2 in an in vitro assay, but fails to inhibit Mtorc1 signaling and results in a loss of catalytic activity in an in vitro assay (PMID: 32502382), and therefore, results in a loss of Tsc2 protein function. |
