Variant summary
Our verdict is Likely benign. Variant got -6 ACMG points: 3P and 9B. PM2PP2BP4BP6_Very_Strong
The NM_000368.5(TSC1):āc.2755A>Cā(p.Lys919Gln) variant causes a missense change. The variant allele was found at a frequency of 0.00000274 in 1,461,892 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (ā ā ). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. K919T) has been classified as Uncertain significance.

Hereditary cancer-predisposing syndrome Benign:1
Likely benign, criteria provided, single submitter | clinical testing | Ambry Genetics | May 09, 2023 | This alteration is classified as likely 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. - |
