The incidence of WESa in 3,072 donors in the United States.
The rare red cell antigen, WES(a), which is controlled by an autosomal dominant gene, was reported by Sistonen et al.(1) to have an incidence in the Finnish population of 0.56 percent. A study was undertaken to determine the incidence of the WES(a) antigen within the United States. A total of 3,072 donor samples were obtained for testing from eight different geographical locations. It was determined that the incidence of the WES(a) antigen in the white donor population tested was 2 per 1,610 or 0.12 percent and in the black donor population tested, 7 per 1,460 or 0.48 percent. In the random population the incidence would he 0.29 percent.
