In humans, ethnic groups with higher prevalence of PCA have higher serum androgens concentrations and shorter polyglutamine (CAG) repeat lengths in the androgen receptor (AR) gene. In dogs, shorter CAG-I lengths are associated with increased PCA risk. Objective: To compare serum androgens concentrations in the BdF with other breeds and to determine whether CAG repeats length and plasma androgens concentrations are correlated. Materials and Methods: Androgens were measured in 46 BdF and in 53 other dog breed. Length of CAG-I and CAG-III repeats were measured in 41 BdF and correlated with androgen levels. Results: In the BdF group shorter CAG-I and longer CAG-III repeat lengths were associated with lower androgen concentrations. Conclusion: As the shorter CAG-I repeat is associated with an increased PCA risk, higher androgen concentrations may protect against the development and progression of PCA. ER -
