| Abstract: | TF is a mutant rat strain showing male pseudohermaphroditism controlled by an autosomal single recessive gene (mp). The affected rats show lack of Leydig cells and androgen deficiency. In this study, we performed linkage analysis using F(2) progeny of crosses between TF and BN strains to determine the chromosomal localization of the mp locus. The mp locus was mapped in a 4 cM region of the distal region of rat chromosome 7 between D7Rat3 and D7Rat115 or D7Rat94. Comparison of the linkage map with corresponding regions of the published rat genome sequence revealed several candidate genes for the mp mutation, including the Dhh, Tegt, Gdp3, and Amhr2 genes. |
