The teaching methods were explored to improve the quality of medical genetic teaching for foreign students according to the common problems during the teaching process. The negative effects of communication barriers in medical genetic teaching could be reduced by interactive teaching or problem-based learning in groups， in which the ability to resolve problems by themselves could be improved. In order to improve the teaching systematicness and teaching quality， the teaching contents in class should be from simple to deep， covering genetic laws， pathogenesis， diagnosis and control measure of genetic diseases. From the perspective of practical application and combining with the construction of self-de-signed teaching textbook and cases， the quality of medical genetic teaching ultimately could be further improved.
