RCV002254850 | SCV002525989 | uncertain significance | Noonan syndrome 7 | 2022-01-27 | criteria provided, single submitter | clinical testing | The BRAF c.1858A>G (p.Met620Val) missense variant is absent in gnomAD v2.1.1 (PM2_Supporting; https://gnomad.broadinstitute.org/ ). This variant occurs in a gene where missense variants are more likely to be damaging based on methods described by Lek et al. (PP2; PMID: 27535533). Seven of seven in silico tools predict a benign effect of this variant on protein function (BP4), but to our knowledge these predictions have not been confirmed by functional assays. To our knowledge, this variant has not been reported in individuals with Cardiofaciocutaneous syndrome and Noonan syndrome. In summary, this variant meets criteria to be classified as of uncertain significance based on the ACMG/AMP criteria, as specified by the RASopathy Variant Curation Expert Panel (PMID:29493581): PM2_Supporting, PP3, PP2. |
