Description

Review information on genetic disorders on the National Human Genome Research Institute Site: http://www.genome.gov/.

Choose a genetic disorder that can be inherited from a parent. Write a 525- to 700-word paper on the genetic disorder. Include the following in your paper:

Summarize the Chromosomal Theory of Inheritance and how chromosomal abnormalities can lead to genetic disorders.

  • Describe the relationship between chromosomes and DNA.
  • Identify an example of a genetic disorder and describe the genetic disorder including symptoms, impact on quality of life, and life expectancy. How common is this disorder? Does it run in specific ethnic bloodlines?

Format your paper according to APA guidelines

Fragile X Syndrome
Fragile X syndrome so far is viewed as the most common inherited disorder. It is not only
to a specific group of people but rather cuts across all borders, ethnicity and racial groups. It is
known to cause intellectual redundancy in both genders, with the ratio of males doubling that of
females. Further studies by various scholars reveal that the major cause of this syndrome is the
FMR1 gene alterations that causes CGG triplet, a DNA segment, to expand (Mazzocco, Quintero,
Murphy, & McCloskey, 2016). Under normal circumstances, the DNA segment is repeated
between four to forty times as opposed to a case of fragile X syndrome patients who experience
the CGG segment for over two hundred times.
This explained abnormal CGG segment expansion inactivates the functioning of the FMR1
gene. An...
