^aNumber of reads for minor allele divided by number of reads for common allele at the gDNA or transcript levels. ^bFold change in allelic expression regardless of which allele is increased in expression. cDNA, complementary DNA; DRG, dorsal root ganglia; gDNA, genomic DNA; SNP, single-nucleotide polymorphism.
