Are there really inbred blue people in Kentucky?

Search: blue people kentucky

Why: Last night, while watching Avatar:

RICHARD - James Cameron said he had to go to Kentucky and find a lizard that could fly just to film this scene.
DAN - Ha, ha.
ME - What?
RICHARD - You know, those blue people in Kentucky.
DAN - What?
ME - This is a real thing?
RICHARD - Yeah, they inbred so much they turned blue.
DAN - Oh, I thought you were making a joke.
ME - Yeah, a weird one.

Answer: Yes! But they weren't really blue because of inbreeding. Not really.

The Fugate family settled on the banks of Troublesome Creek after 1800. Mary, the wife of the patriarch Martin, was a carrier for a rare disease called hereditary methemoglobinemia.

Due to an enzyme deficiency, the blood of met-H victims has reduced oxygen-carrying capacity. Instead of being the usual bright red, arterial blood is chocolate brown and gives the skin of Caucasians a bluish cast.

Some of the Fugates intermarried with the nearby Smiths clan, one of whom also carried met-H. The first "blue Fugate" was born in 1832, and a bunch of cousins popped up thereafter. There were about 6 in the 1890s, and one was reported as recently as 1975.

Here is a nice story about one who was born in 1950s and the hematologist who came to save them all. Other people have had it, too.
