RCV002469054 | SCV002766082 | likely benign | not specified | 2022-11-09 | criteria provided, single submitter | clinical testing | Variant summary: TSC2 c.362C>G (p.Ala121Gly) results in a non-conservative amino acid change located in the Tuberin, N-terminal domain (IPR024584) of the encoded protein sequence. Four of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 5.2e-05 in 251468 control chromosomes, predominantly at a frequency of 0.00038 within the Latino subpopulation in the gnomAD database. The observed variant frequency within Latino control individuals in the gnomAD database is approximately 5.5-fold of the estimated maximal expected allele frequency for a pathogenic variant in TSC2 causing Tuberous Sclerosis Complex phenotype (6.9e-05), strongly suggesting that the variant is a benign polymorphism found primarily in populations of Latino origin. To our knowledge, no occurrence of c.362C>G in individuals affected with Tuberous Sclerosis Complex and no experimental evidence demonstrating its impact on protein function have been reported in the literature. Four clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 and classified the variant as likely benign (n=3) and as uncertain significance (n=1). Based on the evidence outlined above, the variant was classified as likely benign. |
