Genetic Disorders Most individuals are either related to or know someone who is effected by some type of disability. Many of these disabilities are caused by genetic disorders. Genetic disorders may alter physical appearance and cause mild to severe mental retardation. Fragile X syndrome, Down syndrome, Turners syndrome and many other syndromes result from a mutation of a chromosome, an extra chromosome, or too few chromosomes. Discovered in 1991, Fragile X syndrome is considered a fairly new genetic

Genetic disorders are diseases caused when certain mutations occur in DNA. There are a wide range of genetic disorders that are each caused by different genes and each have very different symptoms. There are three kinds of genetic disorders: single-gene disorders, chromosome abnormalities, and multifactorial disorders. In this document we will cover the three types of genetic disorders, examples of each type, and possible treatment of particular disorders such as Huntington’s disease, Down syndrome

Genetic disorders are a topic in biology that can not be avoided. The fact is that genetic disorders can happen in humans, plants or animal. No one and nothing is safe from a genetic disorder. A genetic disorder can appear in the first years off life, or can appear much later in life when least expected. A basic principal of biology states that the behavior of chromosomes during the meiosis process can account for genetic inheritance patterns. There are many reasons for genetic disorders. To start

Various Genetic Disorders Alterations in human chromosomes or the deletion of an important gene product are often due to a mutation, which can spring an abundant strand of genetic mutations and improper coding. Mutations can spring from deletion, duplication or inversion of a chromosome. This improper deletion is the factor that leads to complications and ultimately genetic disorders. Turner Syndrome and Cat-cry Syndrome

11618 “Achondroplasia is a disorder of bone growth. It is the most common form of disproportionate short stature. It occurs in one in every 15,000 to one in 40,000 live births. Achondroplasia is caused by a gene alteration (mutation) in the FGFR3 gene. The FGFR3 gene makes a protein called fibroblast growth factor receptor 3 that is involved in converting cartilage to bone. FGFR3 is the only gene known to be associated with achondroplasia. All people who have only a single copy of the normal FGFR3

number of children are born with biological defects that impair normal function. For THREE of the following conditions, discuss such aspects as the biological cause, the methods of treatment and possible means of detection and/or prevention.One lethal disorder inherited as a recessive allele is Tay-Sachs disease. This is caused by a dysfunctional enzyme that fails to break down brain lipids of a certain class. The symptoms usually become manifest a few months after birth. Some symptoms are seizures, blindness

Cardiofaciocutaneous syndrome is a very rare and serious genetic disorder that generally affects the heart, facial features, and skin of an individual. It is caused by a desultory gene mutation, which takes place in one of four genes. Those genes are known as BRAF, MEK1, MEK2, and KRAS. From research, it is also suspected there is a possibility that other genes are associated with the rare condition. This disorder holds multiple alternative names, a long history, obvious symptoms, extensive amounts

a mutation, a change in a gene or genes. The mutation changes the gene's instructions for making a protein, so the protein does not work properly or is missing entirely. This can cause a medical condition called a genetic disorder. Polydactyly or " many fingered", is a genetic disorder in which humans and animals have an abnormal amount of fingers and toes. In humans and animals, this condition can be present in one or both hands and feet. The extra digit is usually a small piece of soft tissue that

Genetic disorder is a disease caused by a change or mutation in an individual DNA sequence. What exactly caused genetic disorder? It could be because of one mutation in the gene (monogenic disorder), mutation in multiple gene (multifactorial inheritance disorder), combination of gene mutation and environment factor, or damage to the chromosome. The human genome is like a complex set of instruction directing our growth and development; however, it can change. “These changes can affect the individual

Duchenne Muscular Dystrophy is an inherited genetic disorder that consists of extreme muscle weakness, which rapidly worsens, and over time leads to death. Young newlyweds, Molly and Brent are seeking information on the health of their possible children. Molly’s younger brother, Hunter, has Duchenne Muscular Dystrophy, he suffers and is confined to a wheelchair due to this genetic disorder. Molly and Brent want research done on behalf of their future kids, so they can understand the risk they are
