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]

Variant summary: ANKRD1 c.417C>A (p.Phe139Leu) results in a non-conservative amino acid change in the encoded protein sequence. Three of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 0.00052 in 250530 control chromosomes (gnomAD). The observed variant frequency is approximately 21-fold of the estimated maximal expected allele frequency for a pathogenic variant in ANKRD1 causing Cardiomyopathy phenotype (2.5e-05), strongly suggesting that the variant is benign. c.417C>A has been reported in the literature as a VUS in settings of multigene panel testing in an individual affected with Dilated Cardiomyopathy and in cases of sudden cardiac death, without strong evidence for causality (e.g. Pugh_2014, Hertz_2016, Vahatalo_2021). These reports do not provide unequivocal conclusions about association of the variant with Cardiomyopathy. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publications have been ascertained in the context of this evaluation (PMID: 26383259, 24503780, 35087879). ClinVar contains an entry for this variant (Variation ID: 45634). Based on the evidence outlined above, the variant was classified as likely benign. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

Variant classified as Uncertain Significance - Favor Benign. The Phe139Leu varia nt in ANKRD1 has been identified by our laboratory in one individual with DCM, b ut did not segregate with disease in 1 affected relative. In addition, this vari ant has been identified in 1/186 Finnish chromosomes by the 1000 Genomes Sequenc ing Project (http://1000genomes.org; dbSNP rs201398260), though this could repre sent a presymptomatic individual. Phenylalanine (Phe) at this position is not co nserved in mammals or evolutionarily distant species, suggesting that a change a t this position may be tolerated. Additional computational analyses (biochemical amino acid properties, AlignGVGD, PolyPhen2, and SIFT) do not provide strong su pport for or against an impact to the protein. Although this data supports that the Phe139Leu variant may be benign, additional studies are needed to fully asse ss its clinical 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. -
