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]

Dilated cardiomyopathy 1M;C2677491:Hypertrophic cardiomyopathy 12 Uncertain:2
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpJan 24, 2024This sequence change replaces valine, which is neutral and non-polar, with isoleucine, which is neutral and non-polar, at codon 127 of the CSRP3 protein (p.Val127Ile). This variant is present in population databases (rs149201422, gnomAD 0.02%). This missense change has been observed in individual(s) with dilated cardiomyopathy and/or hypertrophic cardiomyopathy (PMID: 27532257, 31983221, 32880476). ClinVar contains an entry for this variant (Variation ID: 44697). 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. 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. -

Uncertain significance, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineFeb 08, 2013The Val127Ile variant in CSRP3 has not been reported in the literature nor previ ously identified by our laboratory. This variant has been identified in 2/4398 A frican American chromosomes from a broad population by the NHLBI Exome Sequencin g Project (http://evs.gs.washington.edu/EVS/; dbSNP rs149201422). This frequency is too low to rule out a role in disease. Computational analyses (biochemical a mino acid properties, conservation, AlignGVGD, PolyPhen2, and SIFT) do not provi de strong support for or against an impact to the protein. In summary, additiona l information is needed to fully assess the clinical significance of the Val127I le variant. -
Cardiovascular phenotype Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 28, 2020The c.379G>A (p.V127I) alteration is located in exon 4 (coding exon 3) of the CSRP3 gene. This alteration results from a G to A substitution at nucleotide position 379, causing the valine (V) at amino acid position 127 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
