Variant summary

Our verdict is Benign. The variant received -8 ACMG points: 1P and 9B. PP3BP6BS1BS2

The NM_001134363.3(RBM20):c.364C>A(p.Gln122Lys) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000122 in 1,551,654 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic 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. Q122E) has been classified as Uncertain significance.

The p.Q122K variant (also known as c.364C>A), located in coding exon 2 of the RBM20 gene, results from a C to A substitution at nucleotide position 364. The glutamine at codon 122 is replaced by lysine, an amino acid with similar properties. This amino acid position is conserved. In addition, this alteration is predicted to be deleterious by in silico analysis. Based on the available evidence, the clinical significance of this variant remains unclear. -
