G6PD and Gaucher disease: Of note, we identified the c.70C>T (p.Arg24*) nonsense mutation, in hemizygosity, in the X‐linked G6PD gene of a male Gaucher patient who was also a compound heterozygote for the pathogenic mutations c.1226A>G (p.Asn409Ser) and c.1448T>C (p.Leu483Pro) (formerly N370S and L444P, respectively) in GBA. Assay of glucose‐6‐phosphate dehydrogenase activity in blood indicated pathologic levels of active enzyme (2.8 U/g of hemoglobin (Hb); normal range: 4.6‐13.5 U/g of Hb), confirming the genetic diagnosis of glucose‐6‐phosphate dehydrogenase deficiency, in addition to Gaucher disease.
