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]

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The p.Y274H variant (also known as c.820T>C), located in coding exon 8 of the ANKRD1 gene, results from a T to C substitution at nucleotide position 820. The tyrosine at codon 274 is replaced by histidine, an amino acid with similar properties. This amino acid position is not well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. The evidence for this gene-disease relationship is limited; therefore, the clinical significance of this alteration is unclear.

Significance:Likely benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

Variant summary: ANKRD1 c.820T>C (p.Tyr274His) results in a conservative amino acid change in the encoded protein sequence. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change. The variant allele was found at a frequency of 0.00013 in 1613968 control chromosomes in the gnomAD database, including 1 homozygotes. The observed variant frequency is approximately 5.15 fold of the estimated maximal expected allele frequency for a pathogenic variant in ANKRD1 causing Cardiomyopathy phenotype (2.5e-05). To our knowledge, no occurrence of c.820T>C in individuals affected with Cardiomyopathy and no experimental evidence demonstrating its impact on protein function have been reported. ClinVar contains an entry for this variant (Variation ID: 180276). Based on the evidence outlined above, the variant was classified as likely benign.
