This sequence change replaces isoleucine with valine at codon 32 of the RAF1 protein (p.Ile32Val). The isoleucine residue is highly conserved and there is a small physicochemical difference between isoleucine and valine. This variant is present in population databases (rs372738063, ExAC 0.03%), and has an allele count higher than expected for a pathogenic variant (PMID: 28166811). This variant has been observed in individual(s) with acute lymphoblastic leukemia (PMID: 26580448). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site, but this prediction has not been confirmed by published transcriptional studies. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
