Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine RCV000037688 SCV000061350 benign not specified 2015-03-21 criteria provided, single submitter clinical testing c.321-14_321-13insT in intron 3 of RAF1: This variant is not expected to have cl inical significance because it has been identified in 6.7% (573/8544) of East As ian chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinst itute.org; dbSNP rs202103447).
GeneDx RCV000680305 SCV000209005 benign not provided 2018-05-31 criteria provided, single submitter clinical testing This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease.

Women's Health and Genetics/Laboratory Corporation of America, LabCorp RCV000037688 SCV001362801 benign not specified 2019-08-19 criteria provided, single submitter clinical testing Variant summary: RAF1 c.321-14dupT alters a non-conserved nucleotide located close to a canonical splice site and therefore could affect mRNA splicing, leading to a significantly altered protein sequence. 5/5 computational tools predict no significant impact on normal splicing. However, these predictions have yet to be confirmed by functional studies. The variant allele was found at a frequency of 0.0088 in 281456 control chromosomes in the gnomAD database, including 81 homozygotes. The observed variant frequency is approximately 350 fold of the estimated maximal expected allele frequency for a pathogenic variant in RAF1 causing Noonan Syndrome and Related Conditions phenotype (2.5e-05), strongly suggesting that the variant is benign. To our knowledge, no occurrence of c.321-14dupT in individuals affected with Noonan Syndrome and Related Conditions and no experimental evidence demonstrating its impact on protein function have been reported. Three submitters have provided clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation (2x benign and 1x likely benign). Based on the evidence outlined above, the variant was classified as benign.
