Lastly Leigh Syndrome Case Study

Of the many many concepts learned within the case, there were a specific few that stood out among the rest. These would have to be: organelles, mutated genes, and lastly Leigh Syndrome. First off what is an organelle. In cell biology, an organelle is one of several structures with specialized functions, suspended in the cytoplasm of a eukaryotic cell (ScienceDaily, 2015). Organelles are subunits that are found within the nucleus of a eukaryotic cells and are individually divided because they all contain their own lipid bilayers. For example think of a bag of skittles as your cell, each individual skittle inside is an organelle and they are all not stuck together because of their coatings (this would act as the bilayer). Onwards on to mutated gene.
Mutations can occur for a plethora of reasons. They also can occur by 2 special ways. Exogenous or Endogenous. Exogenous factors that can mutate a gene would include but not limited to environmental factors and radiation. As for endogenous errors during DNA replication can cause a genetic change (aka mutation). Last but not certainly limited to Leigh Syndrome. This specific disorder is a neurological disorder sadly. This condition is characterized by progressive loss of mental and movement abilities (psychomotor regression) and typically results in death within a couple of years, usually due to respiratory failure (Genetics Home Reference, 2015) Leigh syndrome can be caused from specifically 1 out of the staggering number of 30 different genes. The mutated organelle of the mitochondrial DNA (the powerhouse of the cell). Sadly the result of having the disorder is mostly fatal and is found to result early within life by approximately the age of two. Only rare case it can go on to
