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.431C>T (p.A144V) alteration is located in exon 3 (coding exon 3) of the PGM5 gene. This alteration results from a C to T substitution at nucleotide position 431, causing the alanine (A) at amino acid position 144 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
