Individuals with tuberous sclerosis have a mutation in either the gene TSC1 or TSC2, and these mutations have an autosomal dominant inheritance pattern.

结节性硬化症患者的TSC1或TSC2基因发了突变，为常染色体显性遗传。

The mutations are inherited in an autosomal recessive pattern, which means that you need mutated genes from both parents to get the disease.

这种变异以常染色体隐性遗传方式遗传，即只有同时遗传父母双方的突变基因才会患病。

Huntington disease is an autosomal dominant genetic disorder, which means that one affected copy of a gene is enough to cause disease.

CF is an autosomal recessive disorder involving the CFTR gene, which stands for " cystic fibrosis transmembrane conductance regulator, " and this gene codes for the CFTR protein.

CF是种常染色体隐形遗传病，涉及CFTR基因；CFTR代表跨膜传导调节基因，它编码了CFTR蛋白。

Now most of these gene mutations are inherited in an autosomal dominant pattern, meaning that one copy of an altered SCA gene is enough to cause the disease.

好，快速回顾：急性间歇性卟啉病是常染色体显性疾病，由血红素合成途径中缺乏卟胆原脱氨酶导致。

CF develops when there's a mutation in the CFTR gene, but because it's autosomal recessive, you need to inherit two mutated CFTR genes, one from mom and one from dad.

CFTR基因突变时会产CF，但它是常染色体隐形遗传的；患者体内两条CFTR突变基因，条来自母亲，另条来自父亲。

As a quick recap: sickle cell disease is an autosomal recessive genetic disease where the beta-globin subunit of hemoglobin is misshapen, which causes red blood cells to sickle when deoxygenated.

好！简要回顾：镰状细胞病，是常染色体隐性遗传病，其中血红蛋白的β-珠蛋白发突变，脱氧情况会导致红细胞镰变。
