During genetic linkage studies of retinitis pigmentosa in a Navajo Amerindian family, an apparent null allele of erythrocyte GPT (GPT0) was observed in a man and 2 of his daughters. This is the fourth description of a (GPT0) allele, the first outside of Europe and the first in the Navajo.
在对一个纳瓦霍印第安人家族进行色素性视网膜炎的基因连锁研究期间，在一名男性及其两个女儿中观察到了明显的红细胞谷丙转氨酶无效等位基因（GPT0）。这是对（GPT0）等位基因的第四次描述，首次在欧洲以外地区发现，也是在纳瓦霍人中首次发现。
