Ambry Genetics	RCV000242956	SCV000319006	likely benign	Cardiovascular phenotype	2018-08-27	criteria provided, single submitter	clinical testing	This alteration is classified as likely 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	RCV000606830	SCV000447181	likely benign	Cardiac arrhythmia, ankyrin-B-related	2018-01-12	criteria provided, single submitter	clinical testing	This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as likely benign is not then subjected to further curation. The score for this variant resulted in a classification of likely benign for this disease.

Women's Health and Genetics/Laboratory Corporation of America, LabCorp	RCV000613422	SCV001361177	benign	not specified	2019-08-13	criteria provided, single submitter	clinical testing	Variant summary: ANK2 c.4745G>A (p.Arg1582Gln) 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 0.00076 in 281862 control chromosomes, predominantly at a frequency of 0.0015 within the Non-Finnish European subpopulation in the gnomAD database. The observed variant frequency within Non-Finnish European control individuals in the gnomAD database is approximately 150 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 a benign polymorphism found primarily in populations of Non-Finnish European origin. c.4745G>A has been reported in the literature to be found in 3 heterozygotes, and their average QTc value was reported to be in the normal range. (Ghouse_2015). This report therefore does not support a pathogenic role for the variant. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Five clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. Four laboratories classified the variant as likely benign, while one classified as VUS. Based on the evidence outlined above, the variant was classified as benign.
