Invitae RCV000022038 SCV001377119 pathogenic Deficiency of UDPglucose-hexose-1-phosphate uridylyltransferase 2023-04-20 criteria provided, single submitter clinical testing For these reasons, this variant has been classified as Pathogenic. This variant disrupts the p.Tyr34 amino acid residue in GALT. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 22461411, 25592817). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. ClinVar contains an entry for this variant (Variation ID: 25112). Disruption of the initiator codon has been observed in individuals with galactosemia (PMID: 27176039, 31194252; Invitae). It has also been observed to segregate with disease in related individuals. This variant is not present in population databases (gnomAD no frequency). This sequence change affects the initiator methionine of the GALT mRNA. The next in-frame methionine is located at codon 49.
