Variant summary

Our verdict is Benign. Variant got -7 ACMG points: 0P and 7B. BP4_ModerateBP6BS2

The NM_001134363.3(RBM20):c.3022C>T(p.Arg1008Trp) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000135 in 1,551,614 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 Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R1008P) has been classified as Uncertain significance.

Feb 17, 2012

Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

Variant classified as Uncertain Significance - Favor Benign. The Arg1008Trp vari ant (RBM20) has not been reported in the literature nor previously identified by our laboratory. Arginine (Arg) at position 1008 is not conserved in mammals and computational analyses (AlignGVGD and PolyPhen2) suggest that a change to trypt ophan (Trp) may impact the protein, though this information is not predictive en ough to rule out pathogenicity. While the lack of conservation in mammals sugges ts that the Arg1008Trp variant may be benign, additional information is needed t o fully assess its clinical significance. -
