Abstract excerpt
We have analyzed DNA from three exons of the human protein-L-isoaspartate(D-aspartate) O-methyltransferase gene in 30 individuals. We present evidence for two polymorphisms in these regions that result in amino acid changes. At a site corresponding to amino acid position 119, we find the ATA codon for Ile at a frequency of 0.77 and the GTA codon for Val at a frequency of 0.23. At the site corresponding to amino...
