Variant summary

Our verdict is Likely pathogenic. The variant received 8 ACMG points: 8P and 0B. PM1 PM2 PM5 PP3 PP5

The NM_001134363.3(RBM20):​c.1913C>A​(p.Pro638Gln) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P638R) has been classified as Likely pathogenic.

ACMG classification

Our verdict: Likely_pathogenic. The variant received 8 ACMG points.

• PM1: In a hotspot region, there are 13 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 2 benign, 12 uncertain in NM_001134363.3
• PM2: Very rare variant in population databases, with high coverage
• PM5: Other missense variant is known to change same aminoacid residue: Variant chr10-110812310-C-G is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 202063.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.84
• PP5: Variant 10-110812310-C-A is Pathogenic according to our data. Variant chr10-110812310-C-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 372651.
