The P261R missense mutation was identified in the RAF1 gene. It has not been published as a pathogenic variant or benign polymorphism, to our knowledge. However, this variant has been observed previously in multiple unrelated patients referred for Noonan syndrome testing. P261R is a non-conservative missense mutation that occurs in a highly conserved portion of the RAF1 gene, at an amino acid residue where many other gain-of-function variants (P261A, P261S and P261L) have also been reported in Noonan syndrome (Pandit et al., 2007 and Razzaque et al., 2007). Therefore, P261R is considered to be a pathogenic variant that is consistent with a diagnosis of an autosomal dominant RAF1-related disorder.
