Autosomal rececieve inheritance This happens when an affected parent has one recessive gene and one dominant gene whereas the other has two recessive genes, which allows two children to get two recessive genes meaning they will not be affected. Whereas the other two have one dominant gene meaning they will be affected by the disease.
A genetic disorder is a mutation in an organisms DNA. It is caused by a change in the sequencing of the nucleotides that make up a specific gene. The genetic disorder can be inherited by offspring, but it may or may not show in the offspring depending on whether the genetic disorder is a dominate or recessive allele. There are many genetic disorders that humans develop and inherit. Some disorders cause improvements within the human species while others cause severe retardation of the human species. In this paper, the genetic disorder Angelman Syndrome will be discussed.
Topic Down Syndrome Specific Purpose Statement: To inform my audience about Down syndrome. Central Idea/Thesis: The most common type of chromosomal condition is Down syndrome and there are a few different types of this condition, along with, several different traits that are displayed with this condition.
Causes of the Disorder This disease is genetically inherited and is a dominant characteristic, therefore unfortunately the offspring of a victim has 50% chance of inheriting the disease.
Study Guide For Double Helix by Nancy Werlin (46 points possible) Part I: Due Friday, January 25th 2013. Type or Hand Write in Ink. Research Huntington’s disease and answer these questions. (10 pts) a. Do this first! What is Huntington’s Disease b. How is it caused on a genetic level? Be specific about the chromosome #, genetic mutation, dominant or recessive, and chance of inheriting the disorder.
This syndrome is from a mutation of a gene on chromosome 15 and this causes problems in the production of fibrillin-1 which is a protein that is an important part of connective tissue. The name for the gene is FBN1. Basically, it is the “glue” that helps to support the tissues in the human body. A child born to a parent with this syndrome has a 50% of having it. However, in the remaining 25%, neither parent has the disease which gives them a 1 in 10,000 chance of having a child with this disorder. When a child of two unaffected parents is born with it then the genetic mutation occurs in either the egg or sperm cell at the time of conception.
Shaylee Whetten Period 5 Genetic Diseases Term Project Cystic Fibrosis is a genetic disease which is progressive and limits breathing ability. The lungs and other organs are affected by a thick buildup of mucus. This mucus traps bacteria which leads lung damage, infections, and respiratory failure. The digestive enzymes being released is prevented, affecting the breakdown of food and nutrients being absorbed. ?More than 30,000 children and adults in the United States have Cystic Fibrosis. 70,000 people worldwide.? (Diagnosed With Cystic Fibrosis, Cystic Fibrosis Foundation) Someone who has Cystic Fibrosis have a defective gene from each parent which produces faulty protein. The CFTR gene is the gene that is mutated causing this. The channel that transports chloride in and out of cells is created by instructions that are created by CFTR gene. The regulation of chloride ions and water are prevented creating the thick mucus formed on the passageways of lungs, pancreas, and other organs. Cystic Fibrosis doesn?t cause learning problems are mobility of the person. Babies with this still develop and grow up normally. The average life expectancy is close to 40 years, and has been increasing in the last fifty years thanks to improved care. ?Chronic coughing, recurring chest colds, wheezing, shortness of breath, frequent sinus infections, and allergies that last all year, are the most common symptoms of Cystic Fibrosis.? (Cystic Fibrosis Symptoms) Since this disease is progressive
mutated so significantly that the immune system was not prepared to fight it. (Peters 4).
General Purpose: To inform Specific Purpose: To let the audience know that Citrullinemia is an inherited disorder that causes ammonia and other toxic substances to accumulate in the blood. Central Idea: Patients who are affected by Citrullinemia know that their bodies are at risk as the ammonia builds up in the
A permanent change in a gene that can be passed on to children. The rare, early-onset familial
Within a year of the examination, two of the three children died. A few years later, one of the children’s parents brought a newly born sibling with the same symptoms to Tay’s clinic; leading Tay to believe whatever the disorder was, quite possibly was hereditary (Cowan 133).
This lack of protein causes deficiencies in the relaying of nerve impulses which then leads to an individual displaying the physical and developmental symptoms specific to this syndrome. Most males and about half of females with a full gene mutation have characteristics such as a narrow face, large ears, a prominent jaw and forehead and unusually flexible fingers, and even flat feet and low muscle tone due to associated problems with connective tissues (National Library of Medicine, 2014). Males tend to have a mild to moderate intellectual disability, while only one-third of affected females are intellectually disabled (National Library of Medicine). Individuals also suffer from behavioral problems that include things such attention-deficit/hyperactivity disorders, obsessive-compulsive fidgeting or impulsive actions, unstable and disproportionate emotional displays, aggressive and self-injurious behavior related to difficult temperament, and features of autism spectrum disorders like hand-flapping and poor eye contact (Hersh & Saul,
My results indicated that I’m heterozygous to carrying Jacobsen syndrome trait. I’m homozygous to having or passing along with brownish eyes and carrying hypertension (or susceptible to getting it). Jacobsen syndrome is when a
1. Tylosis is specific to esophageal cancer. 2. Mutations to RHBDF2 have been linked to the cause of development of this syndrome. This disease is autosomal dominant and will only need one parent to pass on the mutation. They only need one copy of the mutated cell in the genes for it to develop. This disease is characterized by palmoplantar keratoderma and will begin to develop around age ten and then the person will develop cancer after the age of twenty.
Nariel Monteiro CHEM 456 Exploring Protein Structure with the Molecular Visualization FirstGlance in Jmol Introduction: The goal of this experiment was to practice using the FirstGlance in Jmol molecular visualization to examine key structural features of proteins. This work is important because protein structure can be related to function, multiple-sequence alignments and evolutionary
