2911593-2	1989	Either the glutamine codon encoded by the single-copy apoB gene at nucleotide 6666 is transcribed and translated to produce apoB-100 or an RNA-editing mechanism substitutes a uracil for cytosine, altering this glutamine codon (CAA) to a stop codon (UAA), prematurely terminating translation to produce apoB-48.	Uracil	175-181	apolipoprotein B	Rattus norvegicus	54-58	
8246950-1	1993	An RNA editing mechanism modifies apolipoprotein B (apo-B) mRNA in the intestine by converting cytosine at nucleotide (nt) 6666 to uracil.	Uracil	131-137	apolipoprotein B	Rattus norvegicus	34-50
