  • *In silico prediction of probability of damaging mutation by Variant Effect Predictor and Anovar.

  • †Probability of pathogenic mutation by Mutation Taster.

  • ‡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.
