Variant summary
Our verdict is Uncertain significance. Variant got 3 ACMG points: 4P and 1B. PM2PP3_ModerateBP6
The NM_000548.5(TSC2):c.4072C>G(p.Pro1358Ala) variant causes a missense change. The variant allele was found at a frequency of 0.00000186 in 1,612,476 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic 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. P1358L) has been classified as Uncertain significance.

Hereditary cancer-predisposing syndrome Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Dec 01, 2023 | The p.P1358A variant (also known as c.4072C>G), located in coding exon 33 of the TSC2 gene, results from a C to G substitution at nucleotide position 4072. The proline at codon 1358 is replaced by alanine, an amino acid with highly similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. - |
