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	Labcorp Genetics (formerly Invitae), Labcorp	Dec 19, 2021	For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 189147). This premature translational stop signal has been observed in individual(s) with glycogen storage disease type Ib (PMID: 9758626). This variant is present in population databases (rs551439289, gnomAD 0.007%). This sequence change creates a premature translational stop signal (p.Gln218*) 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). -

Likely pathogenic, criteria provided, single submitter	clinical testing	Women's Health and Genetics/Laboratory Corporation of America, LabCorp	Aug 15, 2022	Variant summary: SLC37A4 c.652C>T (p.Gln218X) 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 allele was found at a frequency of 8.1e-06 in 247360 control chromosomes (gnomAD). c.652C>T has been reported in the literature in at least one compound heterozygous individual affected with Glycogen Storage Disease Type Ib (e.g. Veiga-da-Cunha_1998). To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Two clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014. Both laboratories classified the variant as pathogenic (n=1) or likely pathogenic (n=1). Based on the evidence outlined above, the variant was classified as likely pathogenic. -
