A Human Disorder, Involving Dysregulation of Epigenetic Mechanisms Essay

A Human Disorder, Involving Dys command of Epigenetic Mechanisms - Essay vitrineA lot of people having this condition are born with an aperture in the abdomen wall that facilitates the projection of the abdominal organs through the navel. Many infants with BWS have tongues that are abnormally long (macroglossia) which can interpose with swallowing, breathing, and speaking. BWSs other features include abdominal organs that are abnormally large (viscreromegaly), pits or creases in the skin near the ears, kidney abnormalities, and low blood sugar (hypoglycemia) in infant (Baum, et al, 2007 pg 78).The genetic causes of BWS are complex. It results from regulation of genes that is abnormal in a given region of chromosome 11. People usually inherit a champion copy of this chromosome from each parent. In many genes of chromosome 11, each of the two copies of the genes is expressed (turned on) in the cells. However, for some genes, notwithstanding the gene inherited from the father (pate rnal copy) is expressed while for some, the copy inherited from the mother (maternal copy) is the only single expressed. These parent specific differences in the expression of the gene are caused by genomic imprinting phenomenon. Abnormalities which involve genes on chromosome 11 that experience genomic imprinting are the cause of many cases of BWS.Typically, half of the cases are at least(prenominal) caused by changes in the methylation process. In genes that experience genomic imprinting, methylation is among the ways that parents of the gene of the origin are marked at the time of the creation of the egg and sperm cells.
