Therefore, it has been classified as a Variant of Uncertain Significance. 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. 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 disruptive, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has not been reported in the literature in individuals with ST3GAL5-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change replaces aspartic acid with histidine at codon 376 of the ST3GAL5 protein (p.Asp376His). The aspartic acid residue is highly conserved and there is a moderate physicochemical difference between aspartic acid and histidine.
