Brugada syndrome Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Labcorp Genetics (formerly Invitae), Labcorp | Dec 13, 2023 | This sequence change replaces lysine, which is basic and polar, with arginine, which is basic and polar, at codon 647 of the SLMAP protein (p.Lys647Arg). This variant is present in population databases (rs150439110, gnomAD 0.04%), and has an allele count higher than expected for a pathogenic variant. This missense change has been observed in individual(s) with clinical features of Brugada syndrome (PMID: 30847666). ClinVar contains an entry for this variant (Variation ID: 411199). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. - |
not specified Benign:1
Likely benign, criteria provided, single submitter | clinical testing | Women's Health and Genetics/Laboratory Corporation of America, LabCorp | Jun 04, 2024 | Variant summary: SLMAP c.1940A>G (p.Lys647Arg) results in a conservative amino acid change in the encoded protein sequence. Five of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.00023 in 249910 control chromosomes. The observed variant frequency is approximately 40 fold of the estimated maximal expected allele frequency for a pathogenic variant in SLMAP causing Arrhythmia phenotype (6.3e-06). c.1940A>G has been reported in the literature in individuals affected with Brugada syndrome (van Lint_2019). These report(s) do not provide unequivocal conclusions about association of the variant with Arrhythmia. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publication have been ascertained in the context of this evaluation (PMID: 30847666). ClinVar contains an entry for this variant (Variation ID: 411199). Based on the evidence outlined above, the variant was classified as likely benign. - |
