Abstract

We report the clinical, haematological and molecular characteristics of two triose phosphate isomerase deficient patients affected by haemolytic anaemia and neuromuscular impairment. The sequence of complete TPI gene showed the presence of two previously undescribed mutations: c.722 T>C (Phe240Ser) and c.28 insG; each of the two unrelated patients showed the new mutation in compound heterozygosity with the most common variant Glu104Asp. The association of Glu104Asp with c.28 insG resulted in a very severe clinical pattern.
