Variant summary
Our verdict is Uncertain significance. Variant got 0 ACMG points: 3P and 3B. PM2PP2BP4_ModerateBP6
The NM_000368.5(TSC1):c.3215C>T(p.Ala1072Val) variant causes a missense change. The variant allele was found at a frequency of 0.00000205 in 1,461,890 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/21 in silico tools predict 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. A1072S) has been classified as Uncertain significance.

Hereditary cancer-predisposing syndrome Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Dec 04, 2022 | The p.A1072V variant (also known as c.3215C>T), located in coding exon 21 of the TSC1 gene, results from a C to T substitution at nucleotide position 3215. The alanine at codon 1072 is replaced by valine, an amino acid with similar properties. This amino acid position is conserved. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. - |
