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

Verdict is Benign. Variant got -14 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.83).
• BP6: Variant 11-19184943-A-G is Benign according to our data. Variant chr11-19184943-A-G is described in ClinVar as [Likely_benign]. Clinvar id is 178892.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr11-19184943-A-G is described in Lovd as [Benign].
• BS1: Variant frequency is greater than expected in population sas. gnomad4_exome allele frequency = 0.0000463 (67/1446648) while in subpopulation SAS AF= 0.000733 (63/85956). AF 95% confidence interval is 0.000588. There are 0 homozygotes in gnomad4_exome. There are 58 alleles in male gnomad4_exome subpopulation. Median coverage is 29. This position pass quality control queck.

not specified Benign:2

Likely benign, criteria provided, single submitter	clinical testing	GeneDx	Dec 27, 2017	This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. -
