Evidence submitted by expert panel

RASopathy VCEP

The c.674G>A (NM_006939.4(SOS2):c.674G>A (p.Arg225Gln)) variant in RIT1 is a missense variant predicted to cause substitution of arginine by glutamine at amino acid 225. No ACMG/AMP evidence codes are met. In summary, this variant meets the criteria to be classified as uncertain significance for autosomal dominant RASopathy (Version 2.1; 09/17/2024).

BP4

Does not meet threshold for pathogenic readout, well conserved in UCSC, no predicted splice impact

BA1

Present in 0.01885% (3/15918) African/African-American alleles in gnomAD v2.1.1
