by comparing the genomic blot patterns from t5-1 and 6.3.6 dnas , we have shown directly that the loss of haplotype expression was due to deletion of the structural genes and have mapped the structural gene for the hla-dr alpha chain to the chromosomal location ( 6p2105-6p23 ) defined by the 6.3.6 deletion .
