Variant summary

Our verdict is Pathogenic. The variant received 18 ACMG points: 18P and 0B. PM1 PM2 PM5 PP3_Strong PP5_Very_Strong

The NM_001134363.3(RBM20):​c.1906C>A​(p.Arg636Ser) variant causes a missense change. 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 Likely pathogenic (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R636L) has been classified as Likely pathogenic.

ACMG classification

Our verdict: Pathogenic. The variant received 18 ACMG points.

• PM1: In a hotspot region, there are 12 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 2 benign, 14 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 chr10-110812304-G-T is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 2994241.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.942
• PP5: Variant 10-110812303-C-A is Pathogenic according to our data. Variant chr10-110812303-C-A is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 270.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
