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 Uncertain_significance. Variant got 5 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PM4: Nonframeshift variant in NON repetitive region in NM_001134363.3.
• PP3: No computational evidence supports a deleterious effect, but strongly conserved according to phyloP

The p.Thr910_Val914del variant in RBM20 has not been previously reported in indi viduals with cardiomyopathy. Data from large population studies is insufficient to assess its frequency. This variant is a deletion of 5 amino acids at positio n 910-914 in exon 11. It is unclear if this deletion will impact protein functio n. In summary, the clinical significance of the p.Thr910_Val914del variant is un certain. -
