Notes

aka c.242G>A (p.Arg81His)

T;T

Even if asymptomatic, consider being tested for G6PD deficiency and be aware of hemolytic anemia potential when taking certain drugs. See G6PD gene page for more information.

C;T

Carrier but likely to be asymptomatic. However, effects vary in females due to random X chromosome inactivation.
