Chromosome 19 - Keeping things moving

From the creator

EXPLORE THE RI ADVENT CALENDAR: http://rigb.org.uk/advent We all need a bit of cholesterol as it's used in our cell membranes, but too much of it can put us at risk of cardiovascular disease. One of the most dangerous types of cholesterol is low-density lipoproteins (LDLs). Usually LDLs are removed from our bloodstream by LDL receptors -- proteins which are coded for by a gene on chromosome 19. Using the London underground as an analogy, Dr Simon Watt explains how a fault on this gene results in a build up of cholesterol, causing congestion in our arteries and leading to potentially fatal cardiovascular disease. If we understand more about these genes, however, and can identify those with genetically high cholesterol there are simple precautions we can take to avoid trouble.
