title: Serum IgE levels in twins.
abstract: Serum IgE level was determined in 76 monozygous and 81 dizygous like-sexed twin pairs representing adult twins living in the Helsinki area. Monozygous twin pairs were frequently concordant with respect to elevated IgE levels, although some pairs were strikingly discordant, indicating that there is a wide range of phenotypic expression for each genotype.
