In genetic pathology, ''5q22.1'' represents a specific location on the long arm of chromosome 5. Chromosomes are numbered and divided into regions and subregions for easier identification and study. The notation ''5q'' refers to the long arm of chromosome 5, and ''22.1'' represents a particular subregion within that arm. This information is essential in genetic testing and research to identify and understand genetic disorders or traits associated with genes located in this region.
