Novel mutations, including a novel G659A missense mutation, of the FUT1 gene are responsible for the para-Bombay phenotype.

Abstract excerpt

Para-Bombay phenotype, with an estimated incidence of 1 in 8000 in Taiwanese residents based on serological analysis, is caused by aberrant alpha(1,2)-fucosyltransferase function and hence diminished H-antigen synthesis. In an individual with para-Bombay phenotype, DNA sequencing revealed two missense mutations previously reported C658T mutation and a novel G659A mutation. Haplotype analysis with restriction...
