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]

Reported in association with cardiomyopathy; however, specific clinical information was not provided (PMID: 19608031, 31983221, 28082330); In silico analysis supports that this missense variant does not alter protein structure/function; This variant is associated with the following publications: (PMID: 19608032, 23299917, 31983221, 34400558, 28082330, 23572067, 19608031) -

Labcorp Genetics (formerly Invitae), Labcorp

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces isoleucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 280 of the ANKRD1 protein (p.Ile280Val). This variant is present in population databases (rs144770680, gnomAD 0.007%). This missense change has been observed in individual(s) with ANKRD1-related conditions (PMID: 19608031, 31983221). ClinVar contains an entry for this variant (Variation ID: 162746). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt ANKRD1 protein function with a negative predictive value of 80%. Experimental studies have shown that this missense change affects ANKRD1 function (PMID: 19608031, 23572067). 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. -

Significance:Likely benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

Ile280Val in exon 8 of ANKRD1: This variant is not expected to have clinical sig nificance due to a lack of conservation across species, including mammals. Of no te, the variant amino acid, valine (Val), has been identified in 7 other mammals (lemur, rat, mouse, horse, cow, alpaca, and opossum) despite high nearby amino acid conservation. In addition, computational analyses (AlignGVGD, PolyPhen2, SI FT) do not suggest a high likelihood of impact to the protein. Finally, it has b een identified in 3/8600 European American chromosomes from a broad population b y the NHLBI Exome Sequencing Project (http://evs.gs.washington.edu/EVS/; dbSNP r s144770680).

Ambry Genetics

Significance:Likely benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
