Abstract excerpt
We have now determined the molecular genetic basis for the common biochemical polymorphism at the adenosine deaminase (ADA) locus. The ADA*2 allele contains a G to A transition at nt22 (relative to the ATG) that results in substitution of asparagine for aspartic acid at codon 8 (Asp8Asn). Introduction of the nucleotide substitution into an ADA 1 cDNA and transfection into monkey kidney (Cos) cells confirmed that...
