dbSNP rs397516856: CSRP3:p.Lys152Lys (chr11-19185004-C-T) – ACMG Classification: Benign (-16 pts)

Variant summary

Our verdict is Benign. The variant received -16 ACMG points: 2P and 18B. PM1BP4_ModerateBP6_Very_StrongBS1BS2

The NM_001369404.1(CSRP3):c.287G>A(p.Arg96Lys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000118 in 1,614,230 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 8/10 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R96G) has been classified as Uncertain significance.

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]

PM1

In a hotspot region, there are 2 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 3 benign, 13 uncertain in NM_001369404.1

BP4

Computational evidence support a benign effect (MetaRNN=0.14609212).

BP6

Variant 11-19185004-C-T is Benign according to our data. Variant chr11-19185004-C-T is described in ClinVar as Likely_benign. ClinVar VariationId is 44698.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS1

Variant frequency is greater than expected in population eas. GnomAdExome4 allele frequency = 0.0000109 (16/1461858) while in subpopulation EAS AF = 0.000378 (15/39700). AF 95% confidence interval is 0.000233. There are 0 homozygotes in GnomAdExome4. There are 10 alleles in the male GnomAdExome4 subpopulation. Median coverage is 31. This position passed quality control check.

BS2

High AC in GnomAdExome4 at 16 AD,SD gene.
