Variant summary

Our verdict is Uncertain significance. Variant got 1 ACMG points: 2P and 1B. PM2BP4

The NM_001134363.3(RBM20):c.536G>A(p.Gly179Asp) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000258 in 1,551,518 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 Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G179V) has been classified as Uncertain significance.

Feb 10, 2015

The p.Gly179Asp variant in RBM20 has been identified by our laboratory in 1 adul t with HCM who carried a pathogenic variant in another gene that was sufficient to explain the disease. Data from large population studies are insufficient to a ssess the frequency of this variant. Computational prediction tools and conserva tion analysis do not provide strong support for or against an impact to the prot ein. In summary, the clinical significance of the p.Gly179Asp variant is uncerta in. -
