Cytogenetic analysis using qPCR revealed both fibrogenic cytokine matrix metalloproteinase 3 (MMP 3) (1.98×10 5 vs. 755.0, P=0.068) and inflammatory cytokine interleukin 6 (IL 6) (1679.2 vs. 372.8, P=0.062) to be elevated in FS cases as compared to controls. The gene discussed is MMP3; the disease is Feingold syndrome.
