Twenty-four Japanese atopic sibs with asthma and/or rhinitis were test
ed for polymorphic microsatellite repeats of Fc epsilon RI beta on chr
omosome 11q13. Significantly increased sharing of maternal alleles was
found (chi(2) = 5.86, p < 0.025) while no significant sharing was fou
nd for paternal alleles. These findings confirm maternal inheritance o
f atopy at this locus in a non-Caucasian population.
