Genes affected

PGM5 (HGNC:8908): (phosphoglucomutase 5) Phosphoglucomutases (EC 5.2.2.2.), such as PGM5, are phosphotransferases involved in interconversion of glucose-1-phosphate and glucose-6-phosphate. PGM activity is essential in formation of carbohydrates from glucose-6-phosphate and in formation of glucose-6-phosphate from galactose and glycogen (Edwards et al., 1995 [PubMed 8586438]).[supplied by OMIM, Mar 2008]

Ambry Genetics

Feb 15, 2023

The c.94G>A (p.G32S) alteration is located in exon 1 (coding exon 1) of the PGM5 gene. This alteration results from a G to A substitution at nucleotide position 94, causing the glycine (G) at amino acid position 32 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
