As is known, H-Y antigens (male specific minor histompatibility antigens) are a group of minor histocompatibility antigens encoded on the Y-chromosome with homologous H-X antigens on the X-chromosome. H-Y antigens were originally discovered as transplant antigens, and they are only expressed in male individuals without specificity for different tissues and organs. A lot of research results show that H-Y antigens play an important role in the sex selection and identification. The paper reviews the above and discusses the application prospect of H-Y antigen in forensic science.
