PGM5
Chr 9phosphoglucomutase 5
Also known as: PGMRP
PGM5 encodes a component of adherens-type cell-cell and cell-matrix junctions that positively regulates maturation and alignment of myofibrils and promotes sarcomere organization, despite its name suggesting phosphoglucomutase activity which it lacks in vitro. Mutations cause autosomal recessive limb-girdle muscular dystrophy type 2S, characterized by progressive proximal muscle weakness. The gene shows tolerance to loss-of-function variants (pLI near 0), consistent with its recessive inheritance pattern.
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Typical tolerance to LoF variation
Mild missense constraint
The highest-scoring mechanism for this gene is dominant-negative.
Note: In-silico variant effect predictors (SIFT, PolyPhen, REVEL, CADD) may underestimate pathogenicity of missense variants in genes with GOF or DN mechanisms. Consider functional evidence and clinical context.
