Invitae RCV000022206 SCV000825910 uncertain significance Deficiency of UDPglucose-hexose-1-phosphate uridylyltransferase 2018-03-01 criteria provided, single submitter clinical testing This sequence change replaces proline with alanine at codon 265 of the GALT protein (p.Pro265Ala). The proline residue is weakly conserved and there is a small physicochemical difference between proline and alanine. This variant is present in population databases (rs111033764, ExAC 0.001%). This variant has been reported in combination with p.Arg204* in three individuals affected with galactosemia, being proven to be in cis in one of them (PMID: 17041746, 19224951). ClinVar contains an entry for this variant (Variation ID: 25265). 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 tolerated, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
