Abstract

Intersexuality has been reported in pigs and investigations are in progress to identify and physically map the genes involved in sex-reversal. In this study we have mapped on porcine chromosomes seven genes which might be implicated in this developmental pathway. Four genes were mapped by radioactive in situ hybridization: AMH (Anti-Mullerian Hormone) and WT1 (Wilms' Tumor gene 1) were both mapped to pig chromosome 2 (SSC2) in the q14 → q21 and p14 → q11 regions, placental CYP19 (cytochrome P450, subfamily XIX) and FTZF1 (fushi tarazu factor [Drosophila] homolog 1, alias SF1 [steroidogenic factor 1]) to pig chromosome 1 (SSC1) in the q14 → q17 and q210 → q211 regions respectively. Four other genes were regionally located by PCR analysis on a cytogenetically characterized porcine somatic cell hybrid panel: a second CYP19 gene (expressed in embryo) was mapped to porcine 1q12 → q17, AHC (alias DAX1, adrenal hypoplasia congenital) to porcine Xp24, SOX2 and SOX9 (SRY sex determining region Y-box 2 and 9) to 13q23 → q41 and 12p13 → p11 respectively. These results are in global agreement with mapping data available in other mammalian species.
