Deletion (genetics) - Types

Types

Types of deletion include the following:

  • 'Terminal Deletion' - a deletion that occurs towards the end of a chromosome.
  • Intercalary Deletion / Interstitial Deletion - a deletion that occurs from the interior of a chromosome.
  • microdeletion - a relatively small amount of deletion (up to 5kb that could include a dozen genes).

Microdeletion usually can be found in children with physical abnormalities, because large amount of deletion results in immediate abortion.

Famous quotes containing the word types:

    The wider the range of possibilities we offer children, the more intense will be their motivations and the richer their experiences. We must widen the range of topics and goals, the types of situations we offer and their degree of structure, the kinds and combinations of resources and materials, and the possible interactions with things, peers, and adults.
    Loris Malaguzzi (1920–1994)

    He types his laboured column—weary drudge!
    Senile fudge and solemn:
    Spare, editor, to condemn
    These dry leaves of his autumn.
    Robertson Davies (b. 1913)

    The American man is a very simple and cheap mechanism. The American woman I find a complicated and expensive one. Contrasts of feminine types are possible. I am not absolutely sure that there is more than one American man.
    Henry Brooks Adams (1838–1918)
