Among the 12 female G-6-PD-deficient samples, 6 cases were heterozygotes, and the remaining were G-6-PD Viangchan homozygotes (n = 5) and one compound heterozygote (Kaiping/Chinese-5) (Table 2).
Genotyping of 42 G-6-PD-normal samples (13 males and 29 females) revealed 8 heterozygotes (7 being G-6-PD Viangchan and one G-6-PD Canton) (Table 2).
