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]

This sequence change replaces glutamine, which is neutral and polar, with leucine, which is neutral and non-polar, at codon 91 of the CSRP3 protein (p.Gln91Leu). This variant is present in population databases (rs727504436, gnomAD 0.02%). This missense change has been observed in individual(s) with autosomal dominant hypertrophic cardiomyopathy (PMID: 16352453). ClinVar contains an entry for this variant (Variation ID: 178014). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant¬¨‚Ä†is likely to be tolerated. 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. -

The p.Gln91Leu variant in CSRP3 has been reported in 1 individual with HCM (Bos 2006) and was absent from large population studies. Computational prediction too ls and conservation analysis do not provide strong support for or against an imp act to the protein. In summary, the clinical significance of the p.Gln91Leu vari ant is uncertain. -

The p.Q91L variant (also known as c.272A>T), located in coding exon 2 of the CSRP3 gene, results from an A to T substitution at nucleotide position 272. The glutamine at codon 91 is replaced by leucine, an amino acid with dissimilar properties. This variant was reported in an individual with features consistent with hypertrophic cardiomyopathy (Bos JM et al. Mol. Genet. Metab., 2006 May;88:78-85;Theis JL et al. Biochem. Biophys. Res. Commun., 2006 Dec;351:896-902). This amino acid position is not well conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Based on the available evidence, the clinical significance of this variant remains unclear. -
