Labcorp Genetics (formerly Invitae), Labcorp RCV003512006 SCV004296675 pathogenic Tuberous sclerosis 2 2023-10-28 criteria provided, single submitter clinical testing This sequence change replaces leucine, which is neutral and non-polar, with proline, which is neutral and non-polar, at codon 1548 of the TSC2 protein (p.Leu1548Pro). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with clinical features of TSC2-related conditions (Invitae). In at least one individual the variant was observed to be de novo. ClinVar contains an entry for this variant (Variation ID: 65095). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on TSC2 protein function. Experimental studies have shown that this missense change affects TSC2 function (PMID: 21309039). For these reasons, this variant has been classified as Pathogenic.
