Invitae RCV003062204 SCV003440784 likely pathogenic Deficiency of UDPglucose-hexose-1-phosphate uridylyltransferase 2022-01-19 criteria provided, single submitter clinical testing 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. 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 missense change has been observed in individual(s) with galactosemia (PMID: 10399107). This variant is not present in population databases (gnomAD no frequency). This sequence change replaces tryptophan, which is neutral and slightly polar, with arginine, which is basic and polar, at codon 167 of the GALT protein (p.Trp167Arg).
