The genetic basis of the interaction between pyrimidine 5' nucleotidase I deficiency and hemoglobin E.
We have previously described a family in which the interaction between pyrimidine 5' nucleotidase I (P5N-I) deficiency and hemoglobin E resulted in severe haemolytic anaemia. In this study we explored the genetic basis of the severe clinical phenotype and look for evidence of the interaction between these conditions. A P5N-I gene mutation (IVS8 + 1-2delGT) was found in the family, confirming that the severe phenotype results from the interaction between two genetic diseases.
