question: Which diseases are associated with the Yaa gene?
answer: The Y-linked autoimmune accelerating gene mutation (yaa), first discovered in the BXSB mouse strain, is known to accelerate spontaneous autoantibody production and subsequent development of lupus disease. It has also been shown to be associated with various autoimmune conditions such as lupus-like syndrome, collagen induced arthrits and glomerulonephritis.
