Variant summary
Our verdict is Pathogenic. Variant got 18 ACMG points: 18P and 0B. PVS1PM2PP5_Very_Strong
The NM_000548.5(TSC2):c.3685C>T(p.Gln1229Ter) variant causes a stop gained change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Pathogenic (★★). Synonymous variant affecting the same amino acid position (i.e. Q1229Q) has been classified as Likely benign. Variant results in nonsense mediated mRNA decay.

Tuberous sclerosis 2 Pathogenic:2
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Apr 28, 2021 | This sequence change creates a premature translational stop signal (p.Gln1229*) in the TSC2 gene. It is expected to result in an absent or disrupted protein product. For these reasons, this variant has been classified as Pathogenic. Loss-of-function variants in TSC2 are known to be pathogenic (PMID: 10205261, 17304050). This variant has been observed in individuals affected with tuberous sclerosis complex (PMID: 1112665, 28968464, Invitae). ClinVar contains an entry for this variant (Variation ID: 49270). This variant is not present in population databases (ExAC no frequency). - |
