NM_001134363.3:c.2761A>G

Variant summary

Our verdict is Benign. The variant received -9 ACMG points: 2P and 11B. PM1BP4_ModerateBP6BS1BS2

The NM_001134363.3(RBM20):​c.2761A>G​(p.Ile921Val) variant causes a missense change. The variant allele was found at a frequency of 0.0000709 in 1,551,766 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign 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. I921F) has been classified as Uncertain significance.

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -9 ACMG points.

PM1
In a hotspot region, there are 3 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 14 uncertain in NM_001134363.3
BP4
Computational evidence support a benign effect (MetaRNN=0.12370053).
BP6
Variant 10-110821380-A-G is Benign according to our data. Variant chr10-110821380-A-G is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 43999.
BS1
Variant frequency is greater than expected in population amr. GnomAd4 allele frequency = 0.000125 (19/152336) while in subpopulation AMR AF = 0.000523 (8/15300). AF 95% confidence interval is 0.00026. There are 0 homozygotes in GnomAd4. There are 5 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
BS2
High AC in GnomAd4 at 19 AD gene.
