The red blood cells of a Japanese man failed to react with anti-Cra sera and with three Cromer-related sera, B.P., G.T., and K.T.O. His serum reacted with all red blood cells tested except his own. This phenotype, which may represent a null phenotype in the Cromer complex, supports the suggestion that the phenotypes of B.P., G.T., and K.T.O. are Cromer related.
一名日本男性的红细胞与抗-Cra血清以及三种与克罗马血型系统相关的血清（B.P.、G.T.和K.T.O.）均无反应。他的血清与除自身以外所有检测的红细胞发生反应。这种表型可能代表克罗马血型系统中的一种无效表型，支持了B.P.、G.T.和K.T.O.的表型与克罗马血型系统相关的推测。
