fine mapping

Fine mapping is a detailed process in genetics used to identify the specific location of a gene or genetic variant responsible for a particular trait or disease. After initial discovery of a broad region associated with the trait, researchers analyze smaller segments within that area to pinpoint the exact gene or even the exact genetic change involved. This helps in understanding how genetics influence traits and can aid in developing targeted treatments. Essentially, fine mapping narrows down the search from a large genetic region to the precise genetic factor responsible.
