In human, the F9 gene is located on the X chromosome at position q27.1. The gene for<unk>  is located on the X chromosome (Xq27.1-q27.2) and is therefore X-linked recessive: mutations in this gene affect males much more frequently than females. At least 534 disease-causing mutations in this gene have been discovered. The F9 gene was first cloned in 1982 by Kotoku Kurachi and Earl Davie. Polly, a transgenic cloned Poll Dorset sheep carrying the gene for<unk> , was produced by Dr Ian Wilmut at the Roslin Institute in 1997.
