Variant summary
Our verdict is Uncertain significance. Variant got 2 ACMG points: 2P and 0B. PM2
The NM_000548.5(TSC2):c.5371G>A(p.Gly1791Ser) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000000685 in 1,458,912 control chromosomes in the GnomAD database, with no homozygous occurrence. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G1791D) has been classified as Uncertain significance.

Tuberous sclerosis 2 Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | St. Jude Molecular Pathology, St. Jude Children's Research Hospital | Sep 08, 2023 | The TSC2 c.5371G>A (p.Gly1791Ser) missense change is absent in gnomAD v2.1.1 (https://gnomad.broadinstitute.org). The in silico tool REVEL is inconclusive about a pathogenic or benign effect of this variant on protein function, and to our knowledge functional studies have not been performed. To our knowledge, this variant has not been reported in individuals with tuberous sclerosis complex. In summary, the evidence currently available is insufficient to determine the clinical significance of this variant. It has therefore been classified as of uncertain significance. - |
