S ummary . The second and third kindreds with hereditary haemolytic anaemia characterized by marked basophilic stippling of the erythrocytes, increased red‐cell GSH and adenine nucleotides, and ribosephosphate pyrophosphokinase (RPK, PRPP synthetase) deficiency are reported. In each affected subject increased auto‐haemolysis was not corrected by glucose additives in the autohaemolysis test. Despite the clearly hereditary nature of the syndrome, a heterozygous ‘carrier’ state could not be demonstrated in any family members. While autosomal recessive transmission is likely, the genetics remain obscure. The roles of substantial RPK deficiency as either a causative factor or an epiphenomenon is likewise not firmly established.
