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]

Uncertain significance, criteria provided, single submitter	clinical testing	Invitae	Mar 29, 2022	This variant, c.923_934dup, results in the insertion of 4 amino acid(s) of the SLC37A4 protein (p.Met308_Met311dup), but otherwise preserves the integrity of the reading frame. This variant is present in population databases (rs786204477, gnomAD 0.002%). This variant has been observed in individual(s) with glycogen storage disease type Ib (PMID: 9758626, 33977030). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 188799). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -

The SLC37A4 c.923_934dup12 variant is predicted to result in an in-frame duplication (p.Met308_Met311dup). This variant was reported in at least three individuals with Glycogen storage disease 1b and 1c and in at least two of those patients was this variant was observed in a compound heterozygous state with loss of function variant (Veiga-da-Cunha et al. 1998. PubMed ID: 9758626; Halligan et al. 2021. PubMed ID: 33977030). This variant is reported in 0.0016% of alleles in individuals of European (Non-Finnish) descent in gnomAD (http://gnomad.broadinstitute.org/variant/11-118896726-G-GTCATGCCAGCCA). This variant is interpreted as likely pathogenic. -
