Epileptic encephalopathy Uncertain:1
This sequence change replaces valine with isoleucine at codon 2216 of the RYR3 protein (p.Val2216Ile). The valine residue is highly conserved and there is a small physicochemical difference between valine and isoleucine. 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. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has not been reported in the literature in individuals with RYR3-related disease. This variant is present in population databases (rs201633619, ExAC 0.03%). -
