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]

The c.1672A>G (p.T558A) alteration is located in exon 11 (coding exon 11) of the PGM5 gene. This alteration results from a A to G substitution at nucleotide position 1672, causing the threonine (T) at amino acid position 558 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
