Illumina Laboratory Services, Illumina RCV000312958 SCV000437934 uncertain significance Congenital glucose-galactose malabsorption 2017-04-27 criteria provided, single submitter clinical testing The SLC5A1 c.1230C>G (p.Tyr410Ter) variant is a stop-gained variant. A literature search was performed for the gene, cDNA change, and amino acid change. No publications were found based on this search. The p.Tyr410Ter variant is reported at a frequency of 0.00001 in the European (non-Finnish) population of the Exome Aggregation Consortium, but this frequency is based on one allele only in a region of good sequence coverage so it is presumed to be rare. Based on the variant frequency, disease prevalence, disease penetrance, and inheritance mode, this variant could not be ruled out of causing disease. Due to the potential impact of stop-gained variants and the lack of clarifying evidence, this variant is classified as a variant of unknown significance but suspicious for pathogenicity for glucose-galactose malabsorption. This variant was observed by ICSL as part of a predisposition screen in an ostensibly healthy population.
Labcorp Genetics (formerly Invitae), Labcorp RCV000312958 SCV004377514 pathogenic Congenital glucose-galactose malabsorption 2023-12-15 criteria provided, single submitter clinical testing This sequence change creates a premature translational stop signal (p.Tyr410*) in the SLC5A1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in SLC5A1 are known to be pathogenic (PMID: 8563765). This variant is present in population databases (rs200206252, gnomAD 0.002%). This variant has not been reported in the literature in individuals affected with SLC5A1-related conditions. ClinVar contains an entry for this variant (Variation ID: 341251). For these reasons, this variant has been classified as Pathogenic.
