Variant summary
Our verdict is Likely benign. Variant got -6 ACMG points: 0P and 6B. BP4BP6BS2
The NM_000548.5(TSC2):c.2365G>A(p.Val789Ile) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000105 in 1,611,378 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 variant affecting the same amino acid position, but resulting in a different missense (i.e. V789A) has been classified as Likely benign.

Tuberous sclerosis syndrome Uncertain:1Benign:1
Uncertain significance, criteria provided, single submitter | clinical testing | All of Us Research Program, National Institutes of Health | Jan 11, 2024 | - - |
Likely benign, criteria provided, single submitter | clinical testing | Illumina Laboratory Services, Illumina | Sep 25, 2017 | This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases allowed determination this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign. - |

Benign, criteria provided, single submitter | clinical testing | Ambry Genetics | Oct 04, 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. - |
