title: Glutamate pyruvate transaminase null allele (GPT0) in the Navajo.
abstract: 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.
