  • Carrier Of Fragile X Her Mother
    490 words
    Biol 100 Lab Report 2 Gerard Chretien November 12, 2001 I. According to the pedigree for the fragile X syndrome in Mrs. S.'s family it shows that her deceased father neither had nor was a carrier of fragile X. Her mother is a carrier and her uncle is likely to have the disease. She also had a sibling that was either stillborn or aborted. It is possible that this sibling had abnormal chromosomes also, which could be the reason the pregnancy did not reach full term. II. a. Jane should be advised t...
  • Patients And Carriers Of Tay Sachs Disease

    Tay Sachs Disease Tay-Sachs is a genetically inherited disease that which is terminal and incurable. A genetic disease is one which is obtained through hereditary; which basically means they are born with the disease. Tay Sachs is when the body is unable to produce an enzyme necessary for fat metabolism in the nerve cells. Scientifically, Tay-Sachs disease is when harmful quantities of a fatty substance called gangliosides GM 2 gather in the nerve cells of the brain. Infants with Tay-Sachs disea...
  • Babies With Tay Sachs Disease

    Tay-sachs disease is perhaps a very dramatic disease because it strikes most keenly at small children and babies. The disease is very rare and fatal. Tay-sachs is a genetic disorder in which harmful amounts of fatty lipids, known as ganglioside GM 2, is built up in the nerve cells in the brain.

Through Gregor Mendel's studies of genetics, it is possible for people to determine whether or not an individual will inherit a genetic disease. All genetic disorders are recessive traits (Campbell). We have learned that if a parent has a genetic disease and the other parent does not have a genetic disease, all of their children will be carriers, or have the trait, of the disease. If...

    Tay Sachs disease (TSD) What is TSD? TSD is a rare hereditary disease caused by a genetic mutation that leaves the body unable to produce an enzyme (hex A) necessary for fat metabolism in nerve cells, producing central nervous system degeneration. The disease is named for a British ophthalmologist, Warren Tay, who first described the disease, in 1881, and a New York neurologist, Bernard Sachs, who first described the cellular changes and the genetic nature of the disease, in 1887. Tay-Sachs Dise...
