This splice site mutation was found to cause a nonfunctional GABRG2 subunit in affected individuals. [12] According to this study, a point mutation was the culprit for the splice-donor site mutation, which occurred in intron 6. A nonfunctional protein product is produced, leading to the also nonfunctional subunit.
Mutation of a splice site reducing specificity. May result in variation in the splice location, causing insertion or deletion of amino acids, or most likely, a disruption of the reading frame. Displacement of a splice site, leading to inclusion or exclusion of more RNA than expected, resulting in longer or shorter exons.
The different types of splicing mutations in genes. Mutations within the splicing regions of genes can lead to a defective transcript and protein. Depending on where exactly the mutation occurs and which "cryptic" splice site near the original site is chosen for splicing, the specific defect in the transcript and protein will vary.
Splice is a 2009 science fiction horror film directed by Vincenzo Natali and starring Adrien Brody, Sarah Polley, and Delphine Chanéac.The story concerns experiments in genetic engineering being done by a young scientific couple, who attempt to introduce human DNA into their work of splicing animal genes resulting in the creation of a human–animal hybrid.

Mutations within introns and in regions with no known biological function (e.g. pseudogenes, retrotransposons) are generally neutral, having no effect on phenotype – though intron mutations could alter the protein product if they affect mRNA splicing. Mutations that occur in coding regions of the genome are more likely to alter the protein ...
Alternative splicing, alternative RNA splicing, or differential splicing, is an alternative splicing process during gene expression that allows a single gene to produce different splice variants. For example, some exons of a gene may be included within or excluded from the final RNA product of the gene. [ 1 ]
The Spliceman tool has applications in personalized genomic medicine.It has been used in several studies to identify disease-causing mutant alleles. Its applications so far include aid in the location of mutations related to neural tube defects, [7] pustular psoriasis, [8] chronic ear infection, [9] hypercholesterolemia, [10] and several other genetic illnesses.
Starting in the late 1990s, scientists realized they could take advantage of this naturally occurring cellular splicing to downplay genetic mutations into less harmful ones. [1] [2] The mechanism behind exon skipping is a mutation specific antisense oligonucleotide (AON).
