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]
TRAPPC4 (HGNC:19943): (trafficking protein particle complex subunit 4) Involved in autophagy and endoplasmic reticulum to Golgi vesicle-mediated transport. Part of TRAPP complex. [provided by Alliance of Genome Resources, Apr 2022]

Uncertain significance, criteria provided, single submitterclinical testingGeneDxDec 30, 2013p.His390Tyr (CAC>TAC): c.1168 C>T in exon 10 of the SLC37A4 gene (NM_001164277.1) A variant of unknown significance has been identified in the SLC37A4 gene.The H390Y missense substitution has not been published as a mutation, nor has it been reported as a benign polymorphism to our knowledge. The H390Y variant is a non-conservative amino acid substitution as these residues differ in polarity, charge, size and/or other properties and is more likely to impact secondary structure. This change occurs at a position in the SLC37A4 protein that is not highly conserved. In-silico analyses are not consistent in their predictions of whether or not H390Y is damaging to the SLC37A4 protein. Therefore, based on the currently available information, it is unclear whether H390Y is a disease-causing mutation or a rare benign variant. The variant is found in MITONUC-MITOP panel(s). -
Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 16, 2021The p.H390Y variant (also known as c.1168C>T), located in coding exon 8 of the SLC37A4 gene, results from a C to T substitution at nucleotide position 1168. The histidine at codon 390 is replaced by tyrosine, an amino acid with similar properties. This amino acid position is conserved. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
