  2. Deletion (genetics) - Wikipedia

    en.wikipedia.org/wiki/Deletion_(genetics)

    Deletion on a chromosome. In genetics, a deletion (also called gene deletion, deficiency, or deletion mutation) (sign: Δ) is a mutation (a genetic aberration) in which a part of a chromosome or a sequence of DNA is left out during DNA replication. Any number of nucleotides can be deleted, from a single base to an entire piece of chromosome. [1]

  3. Chromosomal deletion syndrome - Wikipedia

    en.wikipedia.org/wiki/Chromosomal_deletion_syndrome

    Chromosomal deletion syndrome. Chromosomal deletion syndromes result from deletion of parts of chromosomes. Depending on the location, size, and whom the deletion is inherited from, there are a few known different variations of chromosome deletions. Chromosomal deletion syndromes typically involve larger deletions that are visible using ...

  4. 13q deletion syndrome - Wikipedia

    en.wikipedia.org/wiki/13q_deletion_syndrome

    13q deletion syndrome. 13q deletion syndrome is a rare genetic disease caused by the deletion of some or all of the large arm of human chromosome 13. Depending upon the size and location of the deletion on chromosome 13, the physical and mental manifestations will vary. It has the potential to cause intellectual disability and congenital ...

  5. 1p36 deletion syndrome - Wikipedia

    en.wikipedia.org/wiki/1p36_deletion_syndrome

    1p36 deletion syndrome is a congenital genetic disorder characterized by moderate to severe intellectual disability, delayed growth, hypotonia, seizures, limited speech ability, malformations, hearing and vision impairment, and distinct facial features. The symptoms may vary, depending on the exact location of the chromosomal deletion.

  6. Elision - Wikipedia

    en.wikipedia.org/wiki/Elision

    e. In linguistics, an elision or deletion is the omission of one or more sounds (such as a vowel, a consonant, or a whole syllable) in a word or phrase. However, these terms are also used to refer more narrowly to cases where two words are run together by the omission of a final sound. [1] An example is the elision of word-final /t/ in English ...

  7. Koolen–De Vries syndrome - Wikipedia

    en.wikipedia.org/wiki/Koolen–de_Vries_syndrome

    Koolen–De Vries syndrome (KdVS), also known as 17q21.31 microdeletion syndrome, is a rare genetic disorder caused by a deletion of a segment of chromosome 17 which contains six genes. This deletion syndrome was discovered independently in 2006 by three different research groups. [1][2][3][4]

  8. Frameshift mutation - Wikipedia

    en.wikipedia.org/wiki/Frameshift_mutation

    A deletion mutation alters every codon following it, and can make protein synthesis stop prematurely by forming a stop codon. Sanger sequencing and pyrosequencing are two methods that have been used to detect frameshift mutations, however, it is likely that data generated will not be of the highest quality.

  9. Gene knockout - Wikipedia

    en.wikipedia.org/wiki/Gene_knockout

    Gene knockout. Gene knockouts (also known as gene deletion or gene inactivation) are a widely used genetic engineering technique that involves the targeted removal or inactivation of a specific gene within an organism's genome. This can be done through a variety of methods, including homologous recombination, CRISPR-Cas9, and TALENs.
