Different races have different genetics and differences in gene expression. Black men and middle eastern men are less neotenous and have higher androgen receptor counts, along with having shorter trinucleotide CAG repeats on average.

I notice on this forum it’s mainly white males, along with asian males, who have longer CAG repeats on average. Does anyone know any black/middle eastern/hispanic person with PFS?
