Frequency of the ESD*5 allele in three ethnic groups in Minnesota

Detection of the ESD*5 gene products was simplified by the use of isoelectric focusing (IEF). Gene frequencies for ESD*5 in whites, blacks and Amerindians from the State of Minnesota were 0.019, 0.002 and 0.000, respectively. The gene frequencies observed in the white data set were similar to those reported for European whites.
