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.346-17_346-10delATTTATTT alters a non-conserved nucleotide located at a position not widely known to affect splicing. Several computational tools predict a significant impact on normal splicing: One predict the variant abolishes a canonical 3' acceptor site. Two predict the variant weakens a canonical 3' acceptor site. However, these predictions have yet to be confirmed by functional studies. The variant allele was found at a frequency of 0.019 in 1269304 control chromosomes in the gnomAD database, including 3441 homozygotes. The observed variant frequency is approximately 755 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.346-17_346-10delATTTATTT 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: 45631). Based on the evidence outlined above, the variant was classified as benign. -

Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.346-17_346-10del variant in ANKRD1 has not been reported in the literature nor previously identified by our laboratory. This variant is located in a rep etitive region in intron 3 that contains several other common deletions and has been detected in 2/100 control chromosomes tested by our laboratory. Based on t he overall evidence for variants affecting this region and its frequency in cont rols this variant is likely benign. -
