Two other studies on HLA in Ov infections in Bong County, Liberia and in Kaduna State, Northern Nigeria, found that both River blindness and cutaneous features of Onchocerciasis (not "classical" NS) were associated with HLA-DQB1*03:01 and DQA1*05:01 [33, 34]. The gene discussed is HLA-DQA1; the disease is onchocerciasis.
