Background: Mutations in the gene encoding LHX4, a homeodomain-containing factor with two LIM domains, are responsible for dominant hypopituitarisms with incomplete penetrance and variable expressivity. To date, only 14 unambiguous LHX4 mutations have been reported. Among those cases, 12 had an absent or ectopic posterior pituitary (EPP) and/or an abnormal sella turcica.Objective and hypotheses: To i) assess the contribution of LHX4 in combined pituitary...
