| Abstract: | We have extended our study of an incomplete variant of multiple endocrine neoplasia Type I (MEN IBurin). In this syndrome, primary hyperparathyroidism and prolactin-secreting adenoma are common, with hormone-secreting pancreatic tumors being rarely seen. The recent localization of the prolactin structural gene to chromosome 6 made further investigation of linkage to HLA of particular interest. Results in 2 multigeneration families exclude close linkage to HLA. We cannot at this time draw any inference regarding linkage of MEN IBurin to the prolactin structural gene. |
