Answer

G6PD deficiency is an X-linked inherited disease that primarily affects men. Women may be affected if they are homozygous, which occurs in populations in which the frequency of G6PD deficiency is quite high. Heterozygous women (carriers) can experience clinical disease as a result of X-chromosome inactivation, gene mosaicism, or hemizygosity.
