Variant summary

Our verdict is Benign. The variant received -11 ACMG points: 0P and 11B. BP4_ModerateBP6BS1BS2

The NM_001134363.3(RBM20):c.1138C>T(p.Arg380Trp) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000245 in 1,551,836 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/20 in silico tools predict 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. R380Q) has been classified as Uncertain significance.

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -11 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.20851219).

BP6

Variant 10-110781747-C-T is Benign according to our data. Variant chr10-110781747-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 470584.

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.0000525 (8/152330) while in subpopulation AFR AF = 0.000144 (6/41590). AF 95% confidence interval is 0.0000626. There are 0 homozygotes in GnomAd4. There are 4 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

High AC in GnomAd4 at 8 AD gene.
