我有这种遗传基因吗

问题:
大夫您好，我姥姥生的孩子有两个是肌营养不良，可我妈妈生了一个男孩一个女孩都没事，我弟弟现在都25岁了，完全正常。我想要孩子，可我不知道我是不是携带者，以前学过遗传，我妈可能是携带者也可能不是携带者，我也可能是，但机率不太大，您觉得呢？在哪可以检查？怎么检查？大概得花多少钱？谢谢！急切想知道。

回答:
　　理论上讲，携带者(女性)的子女中男性1/2是患者，1/2正常，宝宝中1/2正常，1/2为携带者。据此您很容易知道您自己是携带者的机率了。由于该病的突变类型极多，目前尚无绝对可靠的检测携带者的方法。

answer:
Theoretically, people living with (female) male children 1 / 2 patients, 1 / 2 normal, daughter of 1 / 2 normal, 1 / 2 for the carriers. Which you can easily know that your own is the probability of the carriers. As a result of mutations in the type of the disease are in large numbers and there is no absolutely reliable method of detecting carriers.
