Genes affected

SLC37A4 (HGNC:4061): (solute carrier family 37 member 4) This gene regulates glucose-6-phosphate transport from the cytoplasm to the lumen of the endoplasmic reticulum, in order to maintain glucose homeostasis. It also plays a role in ATP-mediated calcium sequestration in the lumen of the endoplasmic reticulum. Mutations in this gene have been associated with various forms of glycogen storage disease. Alternative splicing in this gene results in multiple transcript variants.[provided by RefSeq, Aug 2009]

Review Status:criteria provided, single submitter

Collection Method:clinical testing

Variant summary:The c.593A>T in SLC37A4 gene is a missense change that alters a conserved nucleotide and 2/4 in silico tools predict benign outcome. The variant was observed in the large and broad cohorts of the ExAC project at an allele frequency of 0.36% exclusively in individuals of European descent (0.53%), including 2 homozygous occurrences. This frequency exceeds the maximal expected allele frequency for a pathogenic variant in SLC37A4 gene (0.12%). The variant of interest has been reported in three GSD1b patients (Zappu_2010) who also carried a splice-site mutation in homozygous state, strongly suggesting for benign outcome. In functional studies the variant had normal G6P transport activity (Chen, 2010). In addition, the variant has been reported as Benign/Polymorphism by a clinical laboratory and published reports (Zappu, 2010) Taking together, the variant has been classified as Benign. -

This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. -
