Variant summary
Our verdict is Likely benign. Variant got -5 ACMG points: 3P and 8B. PM2PP3BP6_Very_Strong
The NM_000548.5(TSC2):c.926_927delinsAG(p.Leu309Gln) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. Variant has been reported in ClinVar as Likely benign (★★). Another nucleotide change resulting in same amino acid change has been previously reported as Likely benignin UniProt. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. L309F) has been classified as Likely benign.

Hereditary cancer-predisposing syndrome Benign:1
Benign, criteria provided, single submitter | clinical testing | Ambry Genetics | Jan 15, 2021 | This alteration is classified as benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. - |
