Genes affected
GANAB (HGNC:4138): (glucosidase II alpha subunit) This gene encodes the alpha subunit of glucosidase II and a member of the glycosyl hydrolase 31 family of proteins. The heterodimeric enzyme glucosidase II plays a role in protein folding and quality control by cleaving glucose residues from immature glycoproteins in the endoplasmic reticulum. Expression of the encoded protein is elevated in lung tumor tissue and in response to UV irradiation. Mutations in this gene cause autosomal-dominant polycystic kidney and liver disease.

GANAB Gene-Disease associations (from GenCC):
  • polycystic kidney disease 3 with or without polycystic liver disease
    Inheritance: AD Classification: DEFINITIVE, STRONG Submitted by: Labcorp Genetics (formerly Invitae), Genomics England PanelApp, ClinGen
  • autosomal dominant polycystic kidney disease
