↵‡All patients had macroadenoma, and none of them presented with pituitary apoplexy.
↵§This missense variant affects position 22 in the first tetratricopeptide domain of AIP, a well-conserved position in various tetratricopeptide domain proteins.32 38
AIP, aryl hydrocarbon receptor-interacting protein; MAF, minor allele frequency.
