Genetics of cell-surface antigens: Regional mapping of three components of the human cell-surface antigen complex, Al, on chromosome 11

Abstract
Cytogenetic analysis has been performed on a series of deletion mutations on human chromosome 11 of AL hybrid clones in which specific markers have been lost as a result of treatment with mutagenic agents. Such analysis has localized the three previously identified components of the AL cell-surface antigen complex to the indicated regions of chromosome 11: a1 and a3:11p13 → 11pter; a2: 11q13 → 11qter. Using these methodologies human lactic dehydrogenase A localization on the short arm as reported by others has been confirmed. Evidence is presented provisionally assigning this gene to 11p13 → 11pter.
