Summary Introduction
To identify: A genetic condition that is not found by maternal or newborn screening.
Introduction: Genetic disorder is a condition caused by any abnormalities in genetic content of an individual. Genetic diseases are mainly caused by the single-base mutation. Single base mutations are capable of imparting biochemical, functional, and structural abnormalities in the organism.

- Please find an Image/Graphic to represent sickle cell disease: Use at least two different images to help the audience understand the cause and/or inheritance pattern of the disorder you chose. Include a brief 1-2 sentence caption below each image that gives a description of the image and explains its relevance to your chosen disorder. The two images should NOT convey the same exact information. Ideas of images to use include: karyotypes, pedigrees, DNA sequences, etc. Please note: the images should be specific to your chosen disorder. The 2 required images must be related to cause and/or inheritance pattern. Images of an individual with the disorder will not count toward your 2 required images as they do not contribute to the audience's understanding of cause and/or inheritance pattern.arrow_forwardCarlos was invvolved in a paternity suit before DNA testing was available.

- Huntington disease (HD) is a genetic disorder that usually first appears in middle age and, over time, leads to involuntary movements, impaired speech, difficulty swallowing and speaking, and cognitive decline. There is no cure for HD, and affected individuals eventually die, usually after 10 to 15 years of progressively worsening symptoms. Huntington disease is inherited as an autosomal dominant disorder. Presymptomatic genetic testing for HD is available for people with a family history of the disease. Individuals who have a parent with HD have a 50% chance of inheriting the HD gene and eventually having HD. Some of these individuals want to know if they will eventually get the disease, and they undergo presymptomatic genetic testing. Others do not want to know, given that there is no cure or effective treatment for the disease. If you were at risk for HD, would you want to undergo genetic testing? What are some reasons for and against having a genetic test for HD?arrow_forwardThe following scenario can be seen on Ch 29 Clinical case study on Heredity (27-year-old with normal pregnancy): Mrs. Rodriguez’ blood type is type O, and her husband’s is type A. She is currently pregnant and she would like to know what type of blood her baby will have. For discussion 7 please answer the following questions: What are the genotype and phenotype of Mrs. Rodriguez? What are the genotype and phenotype of Mr. Rodriguez, given that Mr. Rodriguez’s mother has O blood type and his father has A blood type? (use Punnett Square on your worksheet to find out the genotype of Mr. Rodriquez) What is the probability that Mrs. Rodriguez’s baby will have O blood type? A? B? AB?
