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.
在居住于赫尔辛基地区的成年同性双胞胎中,对76对单卵双胞胎和81对双卵双胞胎进行了血清IgE水平测定。单卵双胞胎中IgE水平升高的情况常常是一致的,不过也有一些双胞胎对的差异极为显著,这表明每种基因型都存在广泛的表型表达范围。
