前不久,一位男性患者来到我们诊所,向我叙述了他们家族的遗传病史,并提出了他的要求。患者是男性,26岁,系红绿色盲。他兄弟三人,其大哥与他一样,也是红绿色盲,二哥及其父母为正常人。大哥婚后生一儿子,是正常人。患者的妻子现在怀孕已4个月了,听说我们这里可做羊水细胞染色体检查,能鉴定婴儿性别,因此要求做这种检查,是男胎就要,是女胎就不要。 Not long ago, a male patient came to our clinic, told me about their family’s genetic history, and put forward his request. The patient was male, 26 years old, with a red-green color blindness. His brother, his brother, like his brother, is also a red-green blind, brother and his parents as normal people. Brother married a son after marriage, is normal. The patient’s wife is now pregnant for 4 months, I heard that here we can do amniotic fluid cell chromosome examination, can identify the baby’s gender, so the request to do this test is a male fetus, female fetuses do not want.
