For example, somatic polymorphism in AIB1 polyQ length is a genetic risk factor that influences breast cancer onset [30], [31], while a polyQ longer than 40 or shorter than 22 residues in the androgen receptor is associated to the expansion disease spinobulbar muscular atrophy or constitute a risk factor for the prostate cancer, respectively [32]. Here, NCOA3 is linked to prostate carcinoma.
