✦ Synopsis
Erythrocyte glucose-6-phosphate deficiency is an X-chromosomallinked hereditary trait often associated with hemolytic anemia. This report defines a new variant designated as Gd(-) Chiapas, which was found in a subject with occasional hemolytic jaundice. The red cell enzyme activity of the subject is about 15% of normal. The variant enzyme is thermolabile in vitro and has faster-than-normal anodal electrophoretic mobility and stronger-thannormal substrate affinity. The patient's hemolytic problem might be correlated with instability of the variant enzyme under physiologic stress.
