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]

Submissions by phenotype

ANKRD1-related dilated cardiomyopathy Uncertain:1
Feb 06, 2024
Labcorp Genetics (formerly Invitae), Labcorp
Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

This sequence change replaces proline, which is neutral and non-polar, with serine, which is neutral and polar, at codon 52 of the ANKRD1 protein (p.Pro52Ser). This variant is present in population databases (rs397517248, gnomAD 0.003%). This variant has not been reported in the literature in individuals affected with ANKRD1-related conditions. ClinVar contains an entry for this variant (Variation ID: 45626). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available". The serine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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. -

Cardiovascular phenotype Uncertain:1
Aug 20, 2020
Ambry Genetics
Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

The p.P52S variant (also known as c.154C>T), located in coding exon 2 of the ANKRD1 gene, results from a C to T substitution at nucleotide position 154. The proline at codon 52 is replaced by serine, an amino acid with similar properties. This amino acid position is poorly conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -

not specified Benign:1
Feb 22, 2013
Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine
Significance: Likely benign
Review Status: criteria provided, single submitter
Collection Method: clinical testing

p.Pro52Ser in exon 2 of ANKRD1: This variant is not expected to have clinical si gnificance due to lack of evolutionary conservation. Specifically, 10 mammals ha ve a serine at this position despite nearby amino acid conservation. -
