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]

Pathogenic, criteria provided, single submitter	clinical testing	Baylor Genetics	Jun 22, 2023	- -
Pathogenic, criteria provided, single submitter	clinical testing	Invitae	Dec 01, 2023	This sequence change creates a premature translational stop signal (p.Leu116Alafs*15) in the SLC37A4 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in SLC37A4 are known to be pathogenic (PMID: 9758626, 10940311). This variant is present in population databases (rs782604758, gnomAD 0.003%). This variant has not been reported in the literature in individuals affected with SLC37A4-related conditions. ClinVar contains an entry for this variant (Variation ID: 529223). For these reasons, this variant has been classified as Pathogenic. -
