Invitae RCV003768068 SCV000824373 uncertain significance Absence seizure; Myoclonic epilepsy, juvenile, susceptibility to, 1 2018-09-17 criteria provided, single submitter clinical testing This variant is not present in population databases (ExAC no frequency). 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 tolerated, 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 EFHC1-related disease. This sequence change replaces alanine with threonine at codon 394 of the EFHC1 protein (p.Ala394Thr). The alanine residue is moderately conserved and there is a small physicochemical difference between alanine and threonine.
