<strong>NKX2-1</strong>（NK2 Homeobox 1），别名 <strong>TITF1</strong> 或 <strong>TTF-1</strong>，是一个位于人类 14 号染色体上的同源盒（Homeobox）转录因子基因。它是甲状腺、肺和腹侧前脑（Ventral Forebrain）发育的“<strong>主调控基因</strong>”。在临床病理中，其蛋白产物（即 <strong>[[TTF-1]]</strong>）是诊断<strong>[[肺腺癌]]</strong>和甲状腺癌的金标准标志物。然而，在医学遗传学中，NKX2-1 的胚系突变会导致一种罕见的常染色体显性遗传病——<strong>[[脑-肺-甲状腺综合征]]</strong>，表现为舞蹈病、甲状腺功能减退和呼吸窘迫的三联征。<br />

NKX2-1 是一个具有组织特异性的“同源盒”（Homeobox）基因，它像建筑师一样，在胚胎发育早期界定了三个关键器官的形成：<br />

<p style="margin-bottom: 0; text-align: justify; font-size: 0.95em; color: #334155;"><br />
在大脑发育中，NKX2-1 负责腹侧前脑（Ventral Forebrain）的特化。它指导了<strong>基底核</strong>（Basal Ganglia）中 GABA 能中间神经元的迁移。<br />
<br><strong>缺失后果：</strong> 导致神经元迁移障碍，引起运动协调问题，如<strong>[[舞蹈病]]</strong>（Chorea）。<br />

<br>它是肺上皮细胞分化的决定性因子。它启动了<strong>[[表面活性物质]]</strong>蛋白（SP-A, SP-B, SP-C）的表达，防止肺泡塌陷。<br />
<br><strong>缺失后果：</strong> 严重的新生儿呼吸窘迫综合征（RDS）。</li><br />
<li style="margin-bottom: 12px;"><strong>3. 甲状腺 (Thyroid)：代谢基础</strong><br />
<br>它与 PAX8 协同作用，调控甲状腺球蛋白（Tg）和甲状腺过氧化物酶（TPO）的合成。<br />
<br><strong>缺失后果：</strong> <strong>[[先天性甲状腺功能减退]]</strong>（呆小症）。</li><br />
