Stretches of repeating DNA predispose to systemic sclerosis
Systemic sclerosis is an autoimmune disorder that is characterized by excess deposition of connective tissue in the skin, lungs, kidneys and vessels, resulting in lung, heart and kidney dysfunction. In a new study, researchers from the University of Tsukuba revealed that patients with long stretches of repeat DNA sequences, also called microsatellite repeat polymorphism, in the gene for Friend leukemia integration 1 transcription factor (FLI1) are more likely to develop systemic sclerosis.
