The serum concentrations of immunoglobulin M (IgM) were measured in a sample of 93 monozygotic twin pairs, their spouses, and their offsprings. The hypothesis that the human X chromosome carries genes that control the levels of IgM was tested with two different approaches neither one of which provided conclusive evidence to support the IgM X-linked gene hypothesis.
在93对同卵双胞胎及其配偶和后代的样本中测量了免疫球蛋白M（IgM）的血清浓度。采用两种不同方法对人类X染色体携带控制IgM水平基因这一假说进行了检验，但均未提供确凿证据支持IgM X连锁基因假说。
