Polymelia is a rare birth defect in which the affected individual has more than the usual number of limbs, usually five or more limbs. How common is polymelia in humans. This condition, though common in animals, is very rare in humans. Polymelia is a genetic disease, primarily classified as a birth defect, that mutates an individual to grow more than the usual number of limbs. Case presentation In Holstein cattle, little is known about the etiology of polymelia. . This was the result of a conjoined twin scenario. Conclusion Case presentation We present the case of a six-month-old Hispanic boy born with a lower limb bud on the left posterior thigh. This affects both humans and land mammals. Polymelia is a birth defect in which the affected individual has more than the usual number of limbs. The extra limb is most commonly shrunken and/or deformed. The heart is an empty cone-shaped muscle located between the lungs and behind the sternum (Breastbone). In humans and most land-dwelling vertebrates, this means having five or more limbs. Since a baby inherits half its genes from each biological parent, its physical appearance will be a mix of both. In humans and most land-dwelling animals, this means having five or more limbs. When a baby inherits skin color genes from both biological parents, a mixture of different genes will determine their skin color. This means that the skin color a baby has depends on more than one gene . Diagnostic The three most common causes suggested for polymelia seem to be: Fragile chromosome resulting in chromosomal breaks, or an incompleted conjoined twin, and (in the case of amphibians) parasitic worm infection or high doses of vitamin A. This deformity is generally said to be the result of a partially absorbed conjoined twin. Polymelia is a syndrome in which people are born with extra lower limbs.

The extra limb is most commonly shrunken and/or deformed. Polymelia is a genetic birth defect and type of congenital malformation of the limbs that can sometimes occur in chickens, and is defined as the growth of additional limb(s) attached to various body regions. In this disorder, shrunken limbs and arms are attached to the body parts. The extra limb is most commonly shrunken and/or deformed. . Process. In March 2006, a baby boy identified only as Jie-jie was born in Shanghai with a fully formed third arm: he had two full-sized left arms, one ventral to the other. Polymelia (supernumerary limbs) is an extremely uncommon congenital entity rarely reported in humans [ 1, 2 ], though it is frequently reported in animals [ 3 - 5 ]. Its pathogenesis is heterogeneous and includes incomplete separation of monozygotic twins [ 6 - 8 ]. The term is from Greek - "many", "limbs". There are very few reported cases. What gene or chromosome is affected by . Is polymelia a genetic disorder. The exact cause of this genetic disorder is not known. They do, however, generally have bones and blood in them. The additional limb or limbs are often shrunken in size and/or deformed. This disease dramatically affects all of is victims, with horror-like symptoms. Polymelia, or congenital duplication of a limb, is an extremely rare entity in humans, with few cases reported in the literature. In this congenital defect, the extra limb is most commonly. The defect can also be found in animals. Currently, the three of us are working on designing an upgraded version for the future of the human body, an exoskeleton, or a prosthetic structure, that will seek to enhance every part of our bodies that we consider possible of improvement. Image Source: Wikipedia Neurofibromatosis The exact cause of this genetic disorder is not known. The defect can also be found in animals. In humans, some limb anomalies are inherited and the genes responsible for . Polymelia is a birth defect involving limbs, in which the affected individual has more than the usual number of limbs. It is a type of dysmelia. Can polymelia be passed down? Polymelia, the manifestation of extra limbs or parts of limbs, occurs when there is a developmental duplication in the novel NHL repeat domain containing protein (NHLRC2) gene in Angus cattle. This deformity is generally said to be the result of a partially absorbed conjoined twin.

Two thirds of the heart is located to the left of the body's average line and 1/3 is right (see figure 1). Polymelia in humans How is polymelia inherited. The etiology of polymelia in Holsteins has been suggested to be due to spontaneous (de novo) or inherited genetic mutations, partial development of conjoined twins, fetal or maternal exposure to radiation or toxins, or maternal injuries that disrupt fetal development ( Rousseaux and Ribble, 1988; Kim et al., 2001 ).

The accessory limbs, as they are called, are often incompletely formed. In humans, polymelia (the presence of extra limbs) is a rare condition and information on its occurrence is scarce.
