RCV003042471 | SCV005086137 | uncertain significance | Tuberous sclerosis 2 | 2023-07-16 | criteria provided, single submitter | clinical testing | Based on the classification scheme VCGS_Germline_v1.3.4, this variant is classified as VUS-3C. Following criteria are met: 0102 - Loss of function is a known mechanism of disease in this gene and is associated with tuberous sclerosis-2 (MIM#613254). (I) 0107 - This gene is associated with autosomal dominant disease. (I) 0115 - Variants in this gene are known to have variable expressivity. Clinical manifestations demonstrate great phenotypic variability, where even within families the clinical symptoms can vary significantly among individuals (PMID: 31018109). (I) 0200 - Variant is predicted to result in a missense amino acid change from lysine to glutamic acid. (I) 0251 - This variant is heterozygous. (I) 0302 - Variant is present in gnomAD (v2) <0.001 for a dominant condition (1 heterozygote, 0 homozygotes). (SP) 0309 - An alternative amino acid change at the same position has been observed in gnomAD (v2) (2 heterozygotes, 0 homozygotes). (I) 0503 - Missense variant consistently predicted to be tolerated by multiple in silico tools or not conserved in placental mammals with a minor amino acid change. (SB) 0600 - Variant is located in the annotated tuberin domain (DECIPHER). (I) 0710 - Another missense variant comparable to the one identified in this case has inconclusive previous evidence for pathogenicity. This alternative change (p.(Lys784Arg)) has been reported as a VUS (ClinVar). Another alternative substitution with a higher Grantham score (p.(Lys784Thr)) has also been reported as a VUS (ClinVar). (I) 0807 - This variant has no previous evidence of pathogenicity. (I) 0905 - No published segregation evidence has been identified for this variant. (I) 1007 - No published functional evidence has been identified for this variant. (I) 1205 - This variant has been shown to be maternally inherited (by trio analysis). (I) Legend: (SP) - Supporting pathogenic, (I) - Information, (SB) - Supporting benign |
