Receptor Polymorphisms

Meaning

Receptor polymorphisms are common, inherited variations in the DNA sequence of genes that code for hormone or neurotransmitter receptors, leading to structural or expression differences in the resulting protein. These genetic variations can significantly alter an individual’s cellular sensitivity and response magnitude to circulating endogenous hormones and exogenous therapeutic agents. Understanding these polymorphisms is crucial for explaining inter-individual variability in clinical outcomes and for personalizing hormonal therapies.
