Genes affected

ANKRD1 (HGNC:15819): (ankyrin repeat domain 1) The protein encoded by this gene is localized to the nucleus of endothelial cells and is induced by IL-1 and TNF-alpha stimulation. Studies in rat cardiomyocytes suggest that this gene functions as a transcription factor. Interactions between this protein and the sarcomeric proteins myopalladin and titin suggest that it may also be involved in the myofibrillar stretch-sensor system. [provided by RefSeq, Jul 2008]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

Variant summary: The ANKRD1 c.197G>A (p.Arg66Gln) variant involves the alteration of a non-conserved nucleotide, resulting in a missense change in the ankyrin repeat-containing domain (InterPro). 4/5 in silico tools predict benign outcome for this variant. This variant was found in 116/122204 control chromosomes (ExAC) at a frequency of 0.0009492, which is approximately 28 times the estimated maximal expected allele frequency of a pathogenic ANKRD1 variant (0.0000344), suggesting this variant is likely a benign polymorphism. In gnomAD, the variants allele frequency is 0.001079 (299/ 277022 chromosomes). This variant has been reported in one case who had family history of premature sudden deaths in first-degree relatives (Duboscq-Bidot_EJH_2009). Functional analysis in the same study showed a non-significant, mild effect on transcriptional repression was observed as well as a non-significant increase in cell area in cardiomyocytes, suggesting protein function is not significantly impacted by the variant. In ClinVar, while four clinical labs have classified it as uncertain significance, three have classified it as likely benign. Taken together, based on its allele frequency in general population and the possibility that it is likely to be a functional polymorphism rather than causal variant, this variant is classified as likely benign. -

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: 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. -

Significance: Likely benign

Review Status: criteria provided, single submitter

Collection Method: 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. -
