Detection the MLH3 gene C2531T mutation in oligospermia and azoospermia by 4P-ARMS-PCR / 基础医学与临床

ABSTRACT

Objective Analysing the potential relationship of mismatch repair protein MLH3 gene C2531T mutation with oligospermia and azoospermia cases. Methods Using MLH3 C2531T as an example to establish a method of tetra-primer amplification refractory mutation system-PCR (4P-ARMS-PCR);We chose 81 cases of oligospermia,azoospermia patients and 80 normal controls,detecting MLH3 C2531T both using 4P-ARMS-PCR and PCR-RFLP; randomly to select 20% samples to sequence. Results The results suggested higher prevalence of CT+TT genotypes in patients as compared to the controls and association of T allele with disease(P
