PGM3
Chr 6ARphosphoglucomutase 3
Also known as: AGM1, IMD23, PAGM, PGM 3
The protein catalyzes the conversion of GlcNAc-6-P into GlcNAc-1-P during synthesis of UDP-GlcNAc, a sugar nucleotide critical for multiple glycosylation pathways including protein N- and O-glycosylation. Mutations cause immunodeficiency 23, an autosomal recessive disorder affecting immune system function. The gene shows low constraint against loss-of-function variants (pLI 0.000015, LOEUF 0.653).

Predictions shown for reference only — model trained on dominant genes, not applicable to AR conditions.
The Badonyi & Marsh prediction model was trained exclusively on dominant disease genes. Predictions are not reliable for genes with autosomal recessive inheritance and are shown at reduced opacity for reference only.
