G6PD deficiency mutational profile and haplotype diversity using 6 RFLPs (FokI/PvuII/BspHI/ PstI/BclI/NlaIII) and a (CTT)n microsatellite, were investigated in 70 G6PD-deficient Portuguese individuals. All but one G6PD A-376G/202A variants (44/45) have a single haplotype (+/+/–/+/–/+/195). G6PD Betica376G/968C alleles (n=10) have a single RFLP haplotype (+/–/–/+/–/+) and 4 different (CTT)n repeats. Age estimate...
Four different gene mutations were identified in five unrelated Portuguese patients with pyrimidine 5’-nucleotidase type I (P5’N-I) deficient chronic hemolytic anemia. Mutations 502G®C (168 Gly®Arg), 773T®C (258Ile®Thr) and the insertion of an Alu element in exon 9, leading to skipping of this exon in the mRNA transcript, are newly described mutations whereas mutation 425T®C (142Leu®Pro) has been previously rep...
