Gaucher disease (GD) affects approximately 1/40 000–1/60 000 live births and happens due to mutations in GBA1 (human)/Gba1(mice) that lead to the functional disruption of the encoded lysosomal enzyme, acid β‐glucosidase and the consequent excess tissue accumulation of glucosylceramide (GC).1 The gene discussed is GBA1; the disease is Gaucher disease.
