The genetic mutation causes a buildup of mast cells (a part of your body’s immune system). They’re a type of white blood cell that’s created in your bone marrow. Mast cells are found throughout your body, especially the areas that interact with the outside world. When your mast cells detect germs, allergens, or other threats, they release a chemical compound called histamine to try to protect your body. Urticaria pigmentosa happens when the body’s mast cells release histamines in response to a perceived threat to the immune system. These histamines cause the characteristic swelling and itching of the skin in urticaria pigmentosa.

Earmarking is a longstanding and controversial practice in the U.S. Congress, where parties have historically won support for contentious votes by allocating funds for projects in particular members’ districts.

In other moments, members have sought to win favor by revoking funding for unpopular projects. Earmarking is the practice of setting particular money aside for a specific purpose. The term can be used in several contexts, such as in congressional appropriations of taxpayer funds to individual practices like mental accounting.
