Invitae | RCV000555777 | SCV000631391 | pathogenic | Deficiency of UDPglucose-hexose-1-phosphate uridylyltransferase | 2017-06-27 | criteria provided, single submitter | clinical testing | This sequence change deletes 3 nucleotide and inserts 3 nucleotides in exon 8 of the GALT mRNA (c.790_792invCTA), creating a premature translational stop signal (p.Leu264*) and is expected to result in an absent or disrupted protein product. Loss-of-function variants in GALT are known to be pathogenic (PMID: 22944367). This particular variant has been reported in the literature in several individuals affected with galactosemia (PMID: 11754113, 11261429, Invitae). For these reasons, this variant has been classified as Pathogenic. |
Integrated Genetics/Laboratory Corporation of America | RCV000555777 | SCV000695704 | pathogenic | Deficiency of UDPglucose-hexose-1-phosphate uridylyltransferase | 2020-12-19 | criteria provided, single submitter | clinical testing | Variant summary: GALT c.790_792delinsTAG (p.Leu264X) results in a premature termination codon, predicted to cause a truncation of the encoded protein or absence of the protein due to nonsense mediated decay, which are commonly known mechanisms for disease. Truncations downstream of this position have been classified as pathogenic by our laboratory. The variant was absent in 245500 control chromosomes. c.790_792delinsTAG has been reported in the literature in individuals affected with Galactosemia (example, Elsas_1998, Yang_2002, Demirbas_2019 and an external laboratory database). These data indicate that the variant is likely to be associated with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. One clinical diagnostic laboratory has submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. One laboratory classified the variant as pathogenic citing overlapping evidence utilized in the context of this evaluation. Based on the evidence outlined above, the variant was classified as pathogenic. |
