SLC2A9 and gout: Genetic research has identified a number of loci associated with gout and serum levels of uric acid (UC) in the population.[4–7] Sequence variants of MUC1, SLC17A1, GCKR, ABCG2, and SLC2A9 have all been associated with gout and/or elevated serum UC, but heredity for gout remains incompletely understood.
