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]

Invitae

Oct 13, 2022

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. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt ANKRD1 protein function. ClinVar contains an entry for this variant (Variation ID: 543936). This variant has not been reported in the literature in individuals affected with ANKRD1-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.002%). This sequence change replaces arginine, which is basic and polar, with serine, which is neutral and polar, at codon 100 of the ANKRD1 protein (p.Arg100Ser). -

Ambry Genetics

The p.R100S variant (also known as c.300G>C), located in coding exon 3 of the ANKRD1 gene, results from a G to C substitution at nucleotide position 300. The arginine at codon 100 is replaced by serine, an amino acid with dissimilar properties. This amino acid position is not well 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. -
