Invitae RCV000022061 SCV002228643 pathogenic Deficiency of UDPglucose-hexose-1-phosphate uridylyltransferase 2023-08-31 criteria provided, single submitter clinical testing This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 51 of the GALT protein (p.Arg51Gln). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with galactosemia (PMID: 15841485, 31954591). ClinVar contains an entry for this variant (Variation ID: 35522). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt GALT protein function. This variant disrupts the p.Arg51 amino acid residue in GALT. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 22944367). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic.
