What is the polysomy?
People with polysomy have another copy of the chromosome. The problem may arise during meiosis, cell division that produces sperm and eggs when a pair of chromosomes does not completely separate, resulting in a cell with more or less than a normal number of chromosomes. This may also be caused by translocation or replacement of genetic material between chromosomes. Down syndrome is a widely known disorder that occurs due to another chromosome. Kleinfelter's syndrome is another form of polysomy in which males have extra chromosome X X gender, except X and Y.
Down syndrome Children have a third chromosome associated with a 21. They are often slow students and suffer from various health conditions. The Suggest study that at least half of the infants born with trisomy 21 has heart states that include defects in the wall or septum that divide the heart.
Male children born with Kleinfelter syndrome have three sex chromosomes, xxy, instead of a normal pair of sex chromosomes, xy. Infants may or may not develop symptoms as a result of this abnormality, but tend to have weaker muscles, which prevents them from sitting, crawling or walking as soon as other infants of a similar age. Through puberty, these men grow higher, but slimmer, less well -defined muscles than other men. Teenagers with Kleinfelter can have less body hair and face hair, develop wider hips and have a lack of testosterone production. Testosterone replacement can alleviate problems during adulthood that include diabetes and osteoporosis.
women may have congenital abnormality known as Triple X syndrome, three or more sex chromosomes of X are present. The physical characteristics of the state include long legs and torso, which results in greater height. Girls with this form of polysomia often have learning problems and oneIt eats ways that are emotionally inappropriate for their age. However, many XXX women reach adulthood without social problems. The more chromosomes have a child, the more likely it is to show symptoms.
scientists have found that individuals who show polysomy on chromosomes 3, 17 and 31 may have a greater risk of developing certain types of bladder, breast, lung and skin cancer. Especially women with polysomy 17 may have an increased number of human epidermal growth factor receptors (HER-2), which may increase breast cancer. Cancer stemming from this congenital disorder respond well to anthraquers as part of the chemotherapeutic regime.
