Description

In 2 unrelated Caucasian probands from the United States with marginally elevated QTc and arrhythmia (600919), Mohler et al. (2004) identified a 4877C-A transversion in exon 42 of the ANK2 gene, resulting in a thr1626-to-asn (T1626N) substitution. One proband was a 46-year-old female who had a QTc of 450 msec and had experienced syncope, but had a normal resting heart rate of 72 beats per minute. Her daughter was also heterozygous for the T1626N mutation and died of sudden death at age 19 years with no previous cardiac symptoms; QTc and heart rate data were not available. Two sibs, 2 sons, and the mother of the proband were also carriers of the mutation and had resting QTc in the normal range. At the time of report, these carriers were asymptomatic. The second proband was a 51-year-old male who displayed mildly elevated QTc (450 msec) with sinus arrhythmia (heart rate varying from 50 to 110 beats per minute). Two of his sibs with normal QTc were heterozygous for the T1626N mutation but asymptomatic at the time of report. The T1626N mutation was not observed in 550 control individuals.

Description

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.

Description

ANK2 NM_001148.4 exon 42 p.Thr3744Asn (c.11231C>A): This variant has been reported in the literature in at least 4 individuals with clinical suspicion of arrhythmia (Mohler 2004 PMID:15178757, Lieve 2013 PMID:23631430). However, this variant is present in 0.1% (157/126452) of European alleles in the Genome Aggregation Database (http://gnomad.broadinstitute.org/rs121912705). This variant is present in ClinVar, with conflicting classifications of this variant (Variation ID:18057). Evolutionary conservation and computational predictive tools suggest that this variant may not impact the protein. In summary, data on this variant suggests that this variant does not cause disease, but requires further evidence. Therefore, the clinical significance of this variant is uncertain.
