The arginine residue is weakly conserved and there is a small physicochemical difference between arginine and histidine. This variant is present in population databases (rs111033735, ExAC 0.02%). This variant has been observed in combination with other GALT variants in individuals affected with galactose-1-phosphate uridyltransferase deficiency which is specific for Duarte or classic galactosemia (PMID: 20547145, Invitae). ClinVar contains an entry for this variant (Variation ID: 25227). Experimental studies have shown that this missense change causes partial reduction of enzyme activity in vitro (PMID: 11152465). In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic.
