Introduction: Heterozygous mutations in the AIP gene are associated with young-onset pituitary adenomas while homozygous loss of AIP in animal models is lethal. As early diagnosis could lead to better outcomes, family members of AIP mutation-positive patients need follow up. The R304Q variant is commonly described as pathogenic based on clinical assessment. However, it is also present in the general population (minor-allele-frequency (MAF) 0.0007&#15...

Introduction: Non-syndromic pituitary gigantism can result from AIP mutations and the recently identified Xq26.3 microduplications causing X-LAG.Patients and methods: DNA samples and clinical data were collected from 151 patients with pituitary gigantism. All samples were tested for AIP mutations; AIP mutation negative cases (AIPneg) were screened for Xq26.3 microduplications.Results: Xq26.3 micr...
