Genes affected

RBM20 (HGNC:27424): (RNA binding motif protein 20) This gene encodes a protein that binds RNA and regulates splicing. Mutations in this gene have been associated with familial dilated cardiomyopathy. [provided by RefSeq, Apr 2014]

ACMG classification

Verdict is Benign. Variant got -15 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.66).
• BP6: Variant 10-110781827-C-A is Benign according to our data. Variant chr10-110781827-C-A is described in ClinVar as [Likely_benign]. Clinvar id is 538042.Status of the report is criteria_provided_single_submitter, 1 stars.
• BP7: Synonymous conserved (PhyloP=-0.545 with no splicing effect.
• BS1: Variant frequency is greater than expected in population amr. gnomad4_exome allele frequency = 0.0000193 (27/1399424) while in subpopulation AMR AF= 0.0007 (25/35704). AF 95% confidence interval is 0.000486. There are 0 homozygotes in gnomad4_exome. There are 11 alleles in male gnomad4_exome subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High AC in GnomAdExome at 22 AD gene.
