n.
1. The act of deleting; removal by striking out.
2. Material, such as a word or passage, that has been removed from a body of written or printed matter.

deletion (del)

[dilē′shən]
Etymology: L, deletionum, destruction
the loss of a piece of a chromosome.

de·le·tion

(dĕ-lē'shŭn)
genetics Any spontaneous elimination of part of the normal genetic complement, whether cytogenetically visible (chromosomal deletion) or inferred from phenotypic evidence (point deletion).
[L. deletio, destruction]

deletion

In genetics, the removal of a segment of DNA with joining up of the cut ends. as in the loss of a segment of a chromosome. Deletion of a single BASE PAIR is one of the kinds of point mutation. Deletion of a base pair triplet (codon) will result in a protein with a missing amino acid.

Deletion

The absence of genetic material that is normally found in a chromosome. Often, the genetic material is missing due to an error in replication of an egg or sperm cell.

deletion

in genetics, loss of genetic material from a chromosome.

There is an increasing interest in diagnostic applications of the 9p21 deletion within a cluster of genes that includes cyclin-dependent kinase inhibitor 2A (CDKN2A), cyclin-dependent kinase inhibitor 2B (CDKN2B), and methylthioadenosine phosphorylase (MTAP).

In recent years, there has been growing evidence of the involvement of large-scale deletions in the age-dependent decline of cell or tissue function, since the removal of large essential parts of coding sequences usually results in the loss of the corresponding gene products [3, 6].
