Ambry Genetics	RCV000621823	SCV000735256	benign	Cardiovascular phenotype	2018-04-24	criteria provided, single submitter	clinical testing	This alteration is classified as benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity.

Illumina Laboratory Services, Illumina	RCV000625125	SCV001310935	uncertain significance	Cardiac arrhythmia, ankyrin-B-related	2017-04-27	criteria provided, single submitter	clinical testing	This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. However, the evidence from the literature, in combination with allele frequency data from public databases where available, was not sufficient to rule this variant in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance.
Women's Health and Genetics/Laboratory Corporation of America, LabCorp	RCV000426638	SCV001426961	benign	not specified	2020-07-06	criteria provided, single submitter	clinical testing	Variant summary: ANK2 c.7132G>A (p.Glu2378Lys) results in a conservative amino acid change in the encoded protein sequence. Five of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.0023 in 250666 control chromosomes in the gnomAD database, including 1 homozygote. The observed variant frequency is approximately 230-fold of the estimated maximal expected allele frequency for a pathogenic variant in ANK2 causing Arrhythmia phenotype (1e-05), strongly suggesting that the variant is benign. To our knowledge, no occurrence of c.7132G>A in individuals affected with Arrhythmia and no experimental evidence demonstrating its impact on protein function have been reported. Five clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation, and classified the variant as benign (2x), likely benign (2x) or VUS. Based on the evidence outlined above, the variant was classified as benign.
