Researchers identify genetic basis of tropical foot and leg lymphedema
Wearing shoes and genomics are tied together in strategy to eliminate podoconiosis
Farmers in the highlands of southern Ethiopia scratch out a subsistence living from the region’s volcanic red clay. The soil supports the farms, but fine-grained, volcanic rock particles in the dirt threaten the farmers and their families. Continual exposure of bare feet to the volcanic soil causes 1 in 20 people to develop a painful inflammation of the lower extremities that, over time, leads to foot disfigurement. ... Now, researchers think they know why some 4 million people in at least 10 countries worldwide develop this incapacitating condition. One-fifth carry genetic variants that cause their immune system to react to the volcanic dust.
