Polydactyle Case Essay Example for Free

Polydactyle Case EssayPolydactyle is a genetic disorder that is caused by a gene on chromosome seven. Polydactyle is a condition were an individual has more than five digits per hand. Most cases ar isolated and not related to any other disorder scarce some are related to others. The errors occur during fetal development and they are caused by on several(prenominal) mutations on a gene that is known as chromosome seven. Polydactlyle is Autosomal dominant meaning that an offspring can get this disease by having it passed down from just superstar parent. During normal embryonic development sequence the infant is still in the womb the hand of the infant will most likely form a shape of a paddle. Following sise to seven weeks later the paddle hand will split into digits as we know as fingers also resulting in more toes than normal, more fingers than normal senseless digit on hand and extra digit on foot.

This also means that since the gene is dominant, children who have only one parent with the trait have a 50% chance of inheriting it. However, people in the same family carrying the same gene can have different degrees of Polydactyly.There are a number of treatments that are used for the disorder Polydactyl but many families escape to go one way with the disorder. Mo st families contact a Orthopedic Surgeons or a Plastic Surgeon. This specialist removes there childs extra digit when they are 1 to 2 years of age. But Polydactylyvaries in complexity.
