Genetic mutations significantly influence pituitary gland function, affecting hormone production and leading to various endocrine disorders. Critical genes such as PROP1 and Pit-1 are central to this phenomenon; mutations in these genes often result in combined pituitary hormone deficiency (CPHD), manifesting as a decrease in essential hormones like growth hormone, prolactin, and thyroid-stimulating hormone. The diversity in mutation types - from point mutations to deletions or insertions-contributes to the wide range of phenotypic outcomes observed among patients, emphasizing the complexity of genetic regulation in pituitary function. The variable expressivity and incomplete penetrance associated with these mutations further complicate clinical presentations and treatment strategies. This abstract summarizes current understandings of how genetic alterations disrupt pituitary gland functionality and impact patient health, highlighting the need for ongoing research into targeted genetic therapies to manage these profound effects.
