The syndrome is caused by a deletion on the wretched arm of chromosome five. A number of genes are missing out-of-pocket to the deletion, and each can contribute to the symptoms the child experiences. One of the deleted genes that is know to be involved is referred to as, TERT, or telomerase reverse...If you regard to get a full essay, order it on our website: OrderEssay.net
