The human gene has been localized in close proximity to the interleukin 3 gene within a T helper type 2-associated cytokine gene cluster at chromosome region 5q31, which is known to be associated with interstitial deletions in the 5q- syndrome and acute myelogenous leukemia.<unk>  and IL-3 are separated by an insulator element and thus independently regulated. Other genes in the cluster include those encoding interleukins 4, 5, and 13.
