The condition causes localized chest pain that you can reproduce by pushing on the cartilage in the front of your ribcage. The pain is aggravated by deep breathing , yawning or any movement involving the muscles . Costochondritis is a relatively harmless condition and usually goes away without treatment.
The Genetic Code. The genetic code is the name of the language given to the set of instructions contained in every organismâs DNA. A good comparison is assembly language, which is the low-level programming language used in computers that represents machine code instructions.
The gene responsible for HGPS is called LMNA (pronounced âlamin-aâ). One tiny spelling mistake in the DNA sequenceof LMNA is responsible for Progeria. This type of gene change is called apoint mutation. The LMNA gene normally makes a protein called lamin A,which is an important protein for most cells of our bodies. Lamin A is foundin the cell nucleus (the part of each cell that contains the DNA) and helpsmaintain the shape and function of the cell. In Progeria, the LMNA mutation causes the gene to produce an abnormalLamin A protein called progerin. In children with Progeria, many cells in thebody â such as the blood vessels, skin, and bones â make progerin protein.As the children age, progerin builds up in these cells causing progressivedisease.
