Furthermore, 30% of follicular thyroid carcinomas contain a balanced translocation, t(2;3) (q13;p25), that results in fusion of the PAX8 and peroxisome proliferator-activated receptor γ (PPARG) genes with concomitant expression of a PAX8–PPARγ fusion protein (PPFP). Here, PAX8 is linked to thyroid gland follicular carcinoma.
