[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

To date, NF1 constitutional deletions have been identified with multiple techniques, such as microsatellite analysis with intragenic markers (21-23), interphase fluorescence in situ hybridization (FISH) analysis via the use of probes within and flanking the NF1 gene (11,22,24,25), multiplex ligation-dependent probe amplification (MLPA) with commerciallyavailable kits (23, 26), and arraycomparative genomic hybridization (27).
