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.346-13_346-10delATTT alters a nucleotide located at a position not widely known to affect splicing. Consensus agreement among computation tools predict no significant impact on normal splicing. However, these predictions have yet to be confirmed by functional studies. The variant allele was found at a frequency of 1.9e-05 in 1312712 control chromosomes in the gnomAD database (v4), including 1 homozygotes. This frequency is not significantly higher than estimated for a pathogenic variant in ANKRD1 causing Cardiomyopathy (1.9e-05 vs 2.5e-05), allowing no conclusion about variant significance. To our knowledge, no occurrence of c.346-13_346-10delATTT 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: 201658). Based on the evidence outlined above, the variant was classified as likely benign. -
