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]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -5 ACMG points.

BS1

Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00404 (581/143658) while in subpopulation AFR AF= 0.0141 (555/39422). AF 95% confidence interval is 0.0131. There are 3 homozygotes in gnomad4. There are 276 alleles in male gnomad4 subpopulation. Median coverage is 28. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

BS2
