Stumped, the doctor turned to the medical literature for a clue. He found references to methemoglobinemia dating to the turn of the century, but it
wasn't until he came across E. M. Scott's 1960 report in the Journal of Clinical Investigation (vol. 39, 1960) that the answer began to emerge.
Scott was a Public Health Service doctor at the Arctic Health Research Center in Anchorage who had discovered hereditary methemoglobinemia among
Alaskan Eskimos and Indians. It was caused, Scott speculated, by an absence of the enzyme diaphorase from their red blood cells. In normal people
hemoglobin is converted to methemoglobin at a very slow rate. If this conversion continued, all the body's hemoglobin would eventually be rendered
useless. Normally diaphorase converts methemoglobin back to hemoglobin. Scott also concluded that the condition was inherited as a simple recessive
trait. In other words, to get the disorder, a person would have to inherit two genes for it, one from each parent. Somebody with only one gene would
not have the condition but could pass the gene to a child.
Scott's Alaskans seemed to match Cawein's blue people. If the condition were inherited as a recessive trait, it would appear most often in an inbred
