ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -6 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.32372624).

BS1

Variant frequency is greater than expected in population eas. gnomad4 allele frequency = 0.0000591 (9/152304) while in subpopulation EAS AF= 0.000773 (4/5172). AF 95% confidence interval is 0.000263. There are 0 homozygotes in gnomad4. There are 3 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

BS2

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The p.E787K variant (also known as c.2359G>A), located in coding exon 9 of the RBM20 gene, results from a G to A substitution at nucleotide position 2359. The glutamic acid at codon 787 is replaced by lysine, an amino acid with similar properties. This amino acid position is well conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Based on the available evidence, the clinical significance of this alteration remains unclear. -
