A case of hereditary nonspherocytic hemolytic anemia associated with partial erythrocyte PFK deficiency without muscular symptoms is reported: erythrocyte enzyme activity in the propositus was 60% of normal. Kinetic studies of erythrocyte PFK revealed increased sensitivity to ATP inhibition and decr

✦ Synopsis
We report a hereditary hemolytic anemia associated with a severe erythrocyte pyrimidine 5'-nucleotidase deficiency in a Spanish family of five members in which the parents are first cousins. Both parents exhibited decreased nucleotidase activity without clinical or hematologic abnormalities. Two children (a male and a female) showed severe pyrimidine 5'-nucleotidase deficiency with hemolytic anemia. The remaining child (a male) showed no signs of the disease. The findings strongly suggest an autosomal recessive mode of inheritance in this enzymopathy. This seems to be the first report of pyrimidine 5'-nucleotidase deficiency in Spain.

## Introduction. Erythrocyte pyrimidine 5'-nucleotidase (5"ribonucleotide phosphohydrolase EC 3.1.3.5, P5N) deficiency associated with hereditary nonspherocytic hemolytic anemia was first described by Valentine et al. (1974). We now report three female cases with this deficiency found in a Japanes
A new case of a defect in red cell pyrimidine 5'-nucleotide (P5N) activity was found in a large family from Guadeloupe in the West Indies. The propositus presented a characteristic hemolytic anemia with red cell basophilic stippling, an increased GSH level, and a shift of the peak in absorbance of n
The mutant enzyme of a patient with hereditary pyrimidine 5'-nucleotidase deficiency was analyzed biochemically. Partially purified by DEAE-Sephadex and concentrated by ultrafiltration, the enzyme had a high Km for the substrate uridine monophosphate. Utilization of the substrate cytidine monophosph
