Integrated Genetics/Laboratory Corporation of America RCV000590559 SCV000695989 benign not provided 2017-11-22 criteria provided, single submitter clinical testing Variant summary: The KCNQ1 c.513C>T (p.Tyr171Tyr) variant involves the alteration of a non-conserved nucleotide, resulting in a synonymous change. One in silico tool predicts a damaging outcome for this variant. 5/5 splice prediction tools predict no significant impact on normal splicing. ESE finder predicts that this variant may affect ESE site of SRp55. However, these predictions have yet to be confirmed by functional studies. This variant was found in 240/275760 control chromosomes (gnomAD) at a frequency of 0.0008703, which is approximately 9 times the estimated maximal expected allele frequency of a pathogenic KCNQ1 variant (0.0001), suggesting this variant is likely a benign polymorphism. In addition, multiple clinical diagnostic laboratories/reputable databases classified this variant as likely benign. Taken together, this variant is classified as benign.
