克鲁松氏症候群Crouzon syndrome
“纤维芽细胞生长因子受体（fibroblast growth factor receptor, FGFR）基因群”
这个基因群共有FGFR1、FGFR2及FGFR3三个主要成员，和头颅、脸庞的形成有相当密切的关系，只要其中一个发生突变，就会造成种种的头脸部崎形，克鲁松氏症候群（Crouzon syndrome）便是FGFR2基因有了缺陷所造成的特殊先天性异常。
发病几率 为6万分之一 https://t.cn/RpzsaHS

Pulmonary hypertension is a type of high blood pressure that affects the arteries in your lungs and the right side of your heart.
In one form of pulmonary hypertension, called pulmonary arterial hypertension (PAH), blood vessels in your lungs are narrowed, blocked or destroyed. The damage slows blood flow through your lungs, and blood pressure in the lung arteries rises. Your heart must work harder to pump blood through your lungs. The extra effort eventually causes your heart muscle to become weak and fail
In your lungs, the blood releases carbon dioxide and picks up oxygen. The blood normally flows easily through blood vessels in your lungs (pulmonary arteries, capillaries and veins) to the left side of your heart.
However, changes in the cells that line your pulmonary arteries can cause the walls of the arteries to become stiff, swollen and thick. These changes may slow down or block blood flow through the lungs, causing pulmonary hypertension.
Pulmonary hypertension is classified into five groups, depending on the cause.
Group 1:
Pulmonary arterial hypertension (PAH).
Group 2:
Pulmonary hypertension caused by left-sided heart disease.
Group 3:
Pulmonary hypertension caused by lung disease.
Group 4:
Pulmonary hypertension caused by chronic blood clots.
Group 5:
Pulmonary hypertension triggered by other health conditions.

地图样舌（geographic tongue）是舌的丝状乳头在不同部位出现萎缩及恢复，故又称游走性舌炎（migratory glossitis），是一种原因不明的良性、慢性、浅表性、剥脱性局限性舌炎，可能为常染色显性遗传或是自体免疫系统低下的一种疾病。
和免疫力下降或是过敏体质有关。也有研究指出，干癣或本身有缺乏微量元素锌，或正在怀孕阶段，或是有肠胃道疾病，这些状况都可能与地图舌有关联性 https://t.cn/RpzsaHS
