Abstract
A plasma prealbumin variant with a methionine-for-valine substitution at position 30 is closely associated with familial amyloidotic polyneuropathy (FAP) type I. Secondary ion mass spectrometry of the tryptic digest of a carrier's prealbumin could easily detect an abnormal peptide containing the substitution besides the normal peptide. This is a sensitive and reliable method for the diagnosis of FAP.
摘要
一种在第30位缬氨酸被甲硫氨酸替代的血浆前白蛋白变体与I型家族性淀粉样多神经病（FAP）密切相关。对携带者前白蛋白的胰蛋白酶消化产物进行二次离子质谱分析，除了正常肽段外，很容易检测到含有该替代的异常肽段。这是一种诊断FAP的灵敏且可靠的方法。
