MAUDE data represents reports of adverse events involving medical devices. This maude entry was filed with the FDA on 2018-12-04 for HEA 1.2 BEADCHIP KIT, SLIDE 800-20202-08 manufactured by Bioarray Solutions Ltd..
[129575771]
Sequencing results interpretation: the molecular presence of only adenine at the polymorphic site that is indicative of the kidd (jk) antigen would normally represent a homozygous jkb individual1, as was reported on precisetype hea beadchips heag4955_8 and heag7222_1. However, the individual is also homozygous for a polymorphism of the intron 5 splice acceptor site (ivs5as, isbt=jk*02n. 01, also known as c. 342-1g>a) that silences the expression of the jkb antigen. The silencing of jkb, as first reported by lucien et al. 2, would leave no expression of the jkb antigen on the surface of the erythrocyte. Jknull is listed as a limitation of the precisetype? Hea beadchip test as listed in the package insert (part number 190-20210).
