Molecular analysis indicated that inactivation of H - 2L expression in nearly every null clone resulted from an apparent deletion or rearrangement of 5 ' - flanking and 5 ' - coding H - 2L sequences , with breakpoints consistently mapping to within a 550 bp GC - rich region between exon 1 and the middle of intron 2 .
 GENE: H - 2L; GENE: 5 ' - flanking and 5 ' - coding H - 2L sequences
