Invitae RCV001314310 SCV001504838 uncertain significance Deficiency of galactokinase 2022-02-10 criteria provided, single submitter clinical testing This sequence change replaces proline, which is neutral and non-polar, with serine, which is neutral and polar, at codon 28 of the GALK1 protein (p.Pro28Ser). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with GALK1-related conditions. 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. This variant disrupts the p.Pro28 amino acid residue in GALK1. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 10521295, 10790206, 11978883, 11978884, 12647253, 21290184). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). ClinVar contains an entry for this variant (Variation ID: 1015448).
