Description

This sequence change replaces glycine with arginine at codon 730 of the SCARF2 protein (p.Gly730Arg). The glycine residue is moderately conserved and there is a moderate physicochemical difference between glycine and arginine. The frequency data for this variant in the population databases is not available, as this variant may be reported as separate entries in the ExAC database. This variant has not been reported in the literature in individuals affected with SCARF2-related conditions. Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. 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.
