HLA-A19 (A19) is a human leukocyte antigen HLA-A serotype that may recognize the A29, A30, A31, A32, A33, and A74 serotypes.[1] While these haplotypes are found all over the globe, their combined frequencies are higher in Sub Saharan Africa; frequencies tend to decline away from Africa.
Clinical significance
[edit]HLA-A19 has been implicated in a number of diseases, including renal cell carcinoma, Kaposi's sarcoma, vitiligo, and others; antibodies to HLA-A19 were recorded in 86% of infertile men and 92% of infertile women.[1][2]
