Genes affected

SLC37A1 (HGNC:11024): (solute carrier family 37 member 1) The protein encoded by this gene localizes to the endoplasmic reticulum (ER) membrane. This protein translocates glucose-6-phosphate from the cytoplasm into the lumen of the ER for hydrolysis into glucose by another ER membrane protein. This gene is a member of the solute carrier 37 gene family. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Feb 2016]

Collection Method: clinical testing

The c.25C>T (p.R9C) alteration is located in exon 3 (coding exon 1) of the SLC37A1 gene. This alteration results from a C to T substitution at nucleotide position 25, causing the arginine (R) at amino acid position 9 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
