Now individuals with acute intermittent porphyria have a mutation of the HMBS gene which codes for the enzyme porphobilinogen deaminase.

急性间歇性卟啉病的患者存在HMBS基因的突变；该基因编码卟胆原脱氨酶。

Glucose and heme are the treatments for acute intermittent porphyria as they inhibit aminolevulinic acid synthase, the first enzyme involved in heme synthesis.

葡萄糖和血红素用于治疗急性间歇性卟啉病，他们能抑制氨基乙酰丙酸的合成，即影响参与血红素合成的第一种酶。

The last important thing to keep in mind is that acute intermittent porphyria can be distinguished from the other many porphyrias by the fact that it doesn't cause any photosensitive cutaneous symptoms, like skin blistering when exposed to sunlight.

还需要牢记的是，急性间歇性卟啉病患者一般没有光敏皮肤症状，可区别与许多其他类型的卟啉病：那些患者暴露在光照下时，皮肤会起水疱。
