Testing for MPB Gene?

my brother is two years older than me and has had a receding hair line for a few years he is now 23 my hair is still very thick will i follow the same pattern or could i have been skipped by this gene. Are there any tests that can tell you if you have male pattern baldness genes.

No one has identified the MPB gene(s). I would suspect there is more than one gene responsible for hair loss. The only test available is a miniaturization study which shows the progression of the balding pattern and the degree of hair loss.

Family inheritance seems to evade the logical mind and that alone shows that the responsible genes are probably multiple.
