In a parallel group of 50 control subjects with sellar masses and 4 CTLA4 antibody\u2013treated patients who did not develop evidence of pituitary failure, the candidate HLA subtypes were found in \u223c20% for DQ8 and \u223c48% for DR53, respectively.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion and Relevance:<\/jats:title>\n                  <jats:p>The HLA markers, DQ8 and DR53, were found to be commonly present in patients with LH.
