Predicting Regional Mutability in Antibody V Genes Based Solely on Di- and Trinucleotide Sequence Composition

Abstract excerpt

Somatic mutations are not distributed randomly throughout Ab V region genes. A sequence-specific target bias is revealed by a defined hierarchy of mutability among di- and trinucleotide sequences located within Ig intronic DNA. Here we report that the di- and trinucleotide mutability preference pattern is shared by mouse intronic JH and Jkappa clusters and by human VH genes, suggesting that a common mutation...
