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]

ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.8).

Variant summary: The ANKRD1 c.208-16C>T variant involves the alteration of a non-conserved intronic nucleotide. Mutation taster predicts a benign outcome for this variant. 5/5 splice prediction tools predict no significant impact on normal splicing. However, these predictions have yet to be confirmed by functional studies. This variant was found in 547/108416 control chromosomes (19 homozygotes), predominantly observed in the East Asian subpopulation at a frequency of 0.067417 (509/7550; 18 homozygotes). This frequency is about 1961 times the estimated maximal expected allele frequency of a pathogenic ANKRD1 variant (0.0000344), suggesting this is likely a benign polymorphism found primarily in the populations of East Asian origin. In addition, one clinical diagnostic laboratory has classified this variant as benign. It has also been published as a polymorphism in the literature (Arimura_2009). Taken together, this variant is classified as benign. -
