Genes affected

CSRP3 (HGNC:2472): (cysteine and glycine rich protein 3) This gene encodes a member of the CSRP family of LIM domain proteins, which may be involved in regulatory processes important for development and cellular differentiation. The LIM/double zinc-finger motif found in this protein is found in a group of proteins with critical functions in gene regulation, cell growth, and somatic differentiation. Mutations in this gene are thought to cause heritable forms of hypertrophic cardiomyopathy (HCM) and dilated cardiomyopathy (DCM) in humans. Alternatively spliced transcript variants with different 5' UTR, but encoding the same protein, have been found for this gene. [provided by RefSeq, Jul 2008]

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 sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. ClinVar contains an entry for this variant (Variation ID: 1055352). This missense change has been observed in individual(s) with dilated cardiomyopathy and/or heart failure (PMID: 19412328, 28878402). This variant is present in population databases (rs45552933, gnomAD 0.005%). This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 72 of the CSRP3 protein (p.Gly72Arg). -

The p.G72R variant (also known as c.214G>A), located in coding exon 2 of the CSRP3 gene, results from a G to A substitution at nucleotide position 214. The glycine at codon 72 is replaced by arginine, an amino acid with dissimilar properties. This variant has been reported in a dilated cardiomyopathy (DCM) case and in a third degree atrioventricular block case who had additional cardiac variants detected (Hershberger RE et al. Clin Transl Sci., 2008 May;1:21-6; Liu N et al. Sci Rep., 2017 09;7:10676). This variant has also been seen in an exome cohort, but cardiovascular history was not provided (Andreasen C et al. Eur J Hum Genet., 2013 Sep;21:918-28). This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
