Variant summary
Our verdict is Benign. Variant got -7 ACMG points: 0P and 7B. BP4_ModerateBP6BS2
The NM_000548.5(TSC2):āc.4579T>Cā(p.Phe1527Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000161 in 1,612,604 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 Conflicting classifications of pathogenicity (no stars). Another nucleotide change resulting in same amino acid change has been previously reported as Uncertain significancein ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. F1527S) has been classified as Uncertain significance.

TSC2-related disorder Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | PreventionGenetics, part of Exact Sciences | Oct 17, 2022 | The TSC2 c.4579T>C variant is predicted to result in the amino acid substitution p.Phe1527Leu. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.037% of alleles in individuals of African descent in gnomAD (http://gnomad.broadinstitute.org/variant/16-2135240-T-C) and has conflicting interpretations of benign, likely benign, and uncertain significance in ClinVar (https://www.ncbi.nlm.nih.gov/clinvar/variation/49473/). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. - |

Hereditary cancer-predisposing syndrome Benign:1
Likely benign, criteria provided, single submitter | clinical testing | Ambry Genetics | Aug 12, 2021 | 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. - |
