WHO ARE THEY? "Blue People" are descendants of Martin Fugate, who suffered from a recessive gene which limits or stops the production of the enzyme diaphorase (enzymes that catalyze the reduction of various dyes to act as hydrogen acceptors NADH + NADPH).

What makes them blue? Methemoglobinemia Red blood cells (RBC) from blue people are deficient in NADH diaphorase activity and cannot reduce the oxidized iron in methemoglobin (metHb).

The lack of this enzyme gives people a blueish cast to their skin rather than pink. Lack of oxygen to RBC gives this color.

Interview '"He was almost purple,"' his father, Alva Stacy, recalls." Benjy was born in a maternity ward near Hazard, Kentucky and was rushed by ambulance to a medical clinic in Lexington to find help for his blue problem. Days of testing provided no answers; but then Benjy's grandmother told the doctor a story about the "blue" Fugates. Incredibly, Benjy had inherited a gene dating back over 162 years! Thankfully, Benjy lost his blue shade after a few weeks and the only lingering effects were blue fingernails and lips when he was cold or angry.
