Variant summary
Our verdict is Uncertain significance. Variant got 2 ACMG points: 4P and 2B. PM1PM2BP4BP6
The NM_000548.5(TSC2):c.2465C>T(p.Ala822Val) variant causes a missense change. The variant allele was found at a frequency of 0.00000248 in 1,613,030 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. A822T) has been classified as Uncertain significance.

Hereditary cancer-predisposing syndrome Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | May 06, 2022 | The p.A822V variant (also known as c.2465C>T), located in coding exon 21 of the TSC2 gene, results from a C to T substitution at nucleotide position 2465. The alanine at codon 822 is replaced by valine, an amino acid with similar properties. This amino acid position is not well conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. - |
