Variant summary

Our verdict is Benign. The variant received -7 ACMG points: 0P and 7B. BP4_ModerateBS1_SupportingBS2

The NM_001134363.3(RBM20):c.2147G>A(p.Arg716Gln) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000235 in 1,551,720 control chromosomes in the GnomAD database, including 1 homozygotes. 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. R716W) has been classified as Likely benign.

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -7 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.10744703).

BS1

Variant frequency is greater than expected in population nfe. GnomAdExome4 allele frequency = 0.000253 (354/1399412) while in subpopulation NFE AF = 0.00031 (335/1078976). AF 95% confidence interval is 0.000283. There are 1 homozygotes in GnomAdExome4. There are 175 alleles in the male GnomAdExome4 subpopulation. Median coverage is 32. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

BS2

High AC in GnomAd4 at 11 AD gene.
