76 This test involved nine subjects from the infertile group, revealing the occurrence of the following rare mutations: E217G, T1054A, W356X, D443Y and 3667insTC in males and L997F and R297Q in females and 29 subjects from the control, in which we found: A1009T, D110Y, E826K, G1069R, G1130A, G194V, I556V, L320F, M348K, M82V, P1290T, R117C, R352W, R74W, S42F, S660T, S911R, S912L, T1086A, T582S, V920L and Y89C.
