Kentucky Family's Blue Hue Explained
4 Sep
Summary
- A rare genetic condition caused blue skin in a Kentucky family.
- Methemoglobinemia, a blood disorder, was identified as the cause.
- Family isolation and intermarriage perpetuated the rare gene.
The Fugate family of Kentucky experienced a unique inherited condition that resulted in blue-hued skin. This trait, believed to have originated with Martin Fugate around 1820, persisted for generations within the isolated Troublesome Creek community. The striking blue coloring was eventually identified in the 1960s by Dr. Madison Cawein as methemoglobinemia, a rare blood disorder.
Methemoglobinemia occurs when a higher-than-normal proportion of hemoglobin is converted to methemoglobin, impairing oxygen delivery. This leads to a slate-colored or blue tint on the skin and lips. The condition's prevalence in the Fugate family was attributed to their isolation and a pattern of intermarriage, which amplified the effect of a rare recessive gene passed down through generations.
Dr. Cawein's treatment involved administering methylene blue, which offered temporary relief by restoring a more typical skin color. Daily medication was later recommended to manage the condition. The family's story gained wider attention, particularly after the birth of Benjamin Stacy in 1975, whose pronounced blue skin highlighted the enduring nature of this hereditary trait.
