ex·on

(ek'son),
A portion of DNA that codes for a section of the mature messenger RNA obtained from that DNA, and is therefore expressed ("translated" into protein) at the ribosome.
[ex- + on]

exon

(ĕk′sŏn)
n.
A nucleotide sequence that is found in a gene, codes information for protein synthesis, and is transcribed to messenger RNA.

ex·on′ic adj.

exon

The segment of deoxyribonucleic acid (DNA) in a gene that codes for some part of the messenger ribonucleic acid (RNA). Any segment that is represented in the RNA product. Segments that do not code for RNA are called introns.

exon

or

extron

(‘ex'for expressed) or - the DNA segments of an INTERRUPTED split gene that are transcribed into RNA and then into the gene product. Exons occur along the length of the gene, and are separated by segments called INTRONS whose sequences are also transcribed into RNA. The intron RNA segments are then excised, leaving behind the exon RNA segments that join up to form a functional RNA molecule, a process called RNA SPLICING.

In addition, previous studies have confirmed that several KIT and PDGFRA mutations are associated with the response of GIST to sunitinib, including the KIT exon 9, 11, 13, and 17 mutations and the PDGFRA exon 12, 14, and 18 mutations [14].
The most common mutations found in our study were an inframe deletion (n=78, 48.8%) in exon 19 and a point mutation (L858R) in exon 21 (n=61, 38.1%).
By sequence analysis of all the PAH gene exons and its surrounding sequences in this family, it showed a duplication (insertion) of one adenine nucleotide in the exon 3 at position 335-336 of the cDNA, for homozygous in the patient, and for heterozygous in her parents.
This is the largest study reporting data for Latin American patients (n = 5738), although it should be pointed out when comparing data that only exons 19 and 21 were analyzed by direct sequencing for Argentina, Colombia, Peru, andCostaRica, whilein Mexico andPanama all four exons were evaluated for known mutations by a sensitive commercial kit based on ARMS technology.
Here, we compute and comparatively analyze the sequence features of cassette exons and constitutive exons to find out how they differ and to extract classification features for use in the next step.
Many DMD iPSC lines have been established containing different types of mutations in the dystrophin gene ranging from nonsense mutations to whole exon deletions or duplications (Table 1).
The entire female PD controls revealed pattern B with respect to the two reactions of exon 4 of NURR1 gene, which suggested alteration in the pattern of migration, compared to male controls (Figure 4).
Variants occurring more frequently in exon 11 may be simply explained by the fact that it is the largest exon of the LHCGR gene.
found a SNP locus in the GnRHR gene exon 1 of the Jining Grey goat, which has AA, AB and BB three genotypes, and found that the average litter size of the Jining Grey goats with the BB genotype was larger than that of goats with the AA and AB genotypes (Chu MX et al.
Within the exons of KCNE1, it is known that the last exon, where we found 653 C/T SNPs, participates in encoding protein Mink; thus, 653 C/T SNPs are the coding SNPs (cSNPs).
The MEFV gene is located on the short arm of chromosome 16 and has 10 exons. Most of the disease-causing mutations are located in the 10th exon.
