The investigators found that the diagnosis of diabetes and treatment needed to prevent diabetes complications may be delayed in people who carry the variant, G6PDdef, because it is associated with reduced levels of HbA1c, a widely used clinical marker of blood glucose levels. Testing for genetic variations that cause G6PD deficiency could lead to improvements in Read More
