Brugada syndrome 5 Uncertain:1
This sequence change replaces serine, which is neutral and polar, with tyrosine, which is neutral and polar, at codon 200 of the SCN1B protein (p.Ser200Tyr). This variant is present in population databases (no rsID available, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with SCN1B-related conditions. ClinVar contains an entry for this variant (Variation ID: 406504). 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. -
