Integrated Genetics/Laboratory Corporation of America RCV000587153 SCV000696036 uncertain significance not provided 2016-12-19 criteria provided, single submitter clinical testing Variant summary: The KCNH2 c.773C>T (p.Pro258Leu) variant involves the alteration of a conserved nucleotide. 3/4 in silico tools predict a damaging outcome for this variant (SNPs&GO not captured due to low reliability index). This variant was not found in 2166 control chromosomes. The variant of interest has not, to our knowledge, been reported in affected individuals via publications and/or reputable databases/clinical diagnostic laboratories; nor evaluated for functional impact by in vivo/vitro studies. An internal sample also carried a pathogenic variant in KCNQ1 c.502G>A/p.Gly168Arg. Because of the absence of clinical information and the lack of functional studies, the variant is classified as a variant of uncertain significance (VUS) until additional information becomes available.
