The rare MNS antigen Or (MNS31) is sensitive to ficin, papain and sialidase, but partially resistant to trypsin (0.05%); the effect of alpha-chymotrypsin is not known. A point mutation, 204C --> T in exon 3 of GYPA, is associated with the Or+ phenotype. We report here the first case of hemolytic disease of the newborn (HDN) caused by anti-Or, and expand the information on the nature of the Or determinant.
