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]

ANKRD1-related dilated cardiomyopathy Uncertain:1
Aug 29, 2019
Labcorp Genetics (formerly Invitae), Labcorp
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This variant has not been reported in the literature in individuals with ANKRD1-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change replaces leucine with proline at codon 206 of the ANKRD1 protein (p.Leu206Pro). The leucine residue is highly conserved and there is a moderate physicochemical difference between leucine and proline. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. -
