what causes piebaldism


All who inherit the gene have at Piebaldism can be caused by mutations in the KIT and SNAI2 genes. The most common cause of piebaldism is a mutation in the KIT proto-oncogene. Piebaldism is an autosomal dominant hereditary condition, which tends to produce high rates of inheritance and long chains of generational transmission. All who inherit the gene have at some time in life evidence of piebald hypopigmentation of the hair or skin, most likely both. Melanin is the pigment responsible for the colour of the skin and hair. The condition leads to the presence One leading theory held that the patterns were caused by the mutated Kit gene slowing down the migration of In particular, mutations may affect: In this article in detail we will consider "piebaldism". Piebaldism is a hereditary phenomenon that is common in animals, partly due to the genetic consequences of selective breeding, but rare in humans.It is the result of a genetic White forelock in 80-90% of those affected ( poliosis) Leukoderma (white patch due to absence of melanocytes) of the central portion of the forehead. The constant signaling causes overproliferation of the cells that make up these tumors. Piebaldism is an uncommon autosomal dominantly inherited pigment anomaly characterized by a congenital white forelock and leukoderma on the frontal scalp, forehead, ventral trunk and extremities. Causes, symptoms, diagnosis, treatment will also be described. In this article in detail we will consider "piebaldism". It is also known as Piebaldism is an autosomal dominant trait that causes patches of non pigmented and hypopigmented skin cells to develop. Examples of trauma are a cut or a blow to an area of the body. It is caused by melanocyte or melanin depletion, or a decrease in the amino acid tyrosine, which is used by melanocytes to
