Missense mRNA molecules are created when template DNA strands or the mRNA strands themselves undergo a missensemutation in which a protein coding sequence is mutated and an altered amino acid sequence is coded for. (wikipedia.org)
A missense mRNA arises from a missensemutation, in the event of which a DNA nucleotide base pair in the coding region of a gene is changed such that it results in the substitution of one amino acid for another. (wikipedia.org)
For example, in knock-in studies, human orthologs are identified in model organisms to introduce missense mutations, or a human gene with a substitution mutation is integrated into the genome of the model organism. (wikipedia.org)

Mode of inheritance predictions - pathogenic for autosomal recessive (AR) disease, pathogenic for autosomal dominant (AD) disease, or benign - for all possible missense variants in the human genome are available at https://github.com/rondolab/MOI-Pred/ . (medrxiv.org)
Nonetheless, the association signal primarily arises from de novo protein-truncating variants, as opposed to the more common missense variants. (springer.com)
Despite their commonness in humans, determining which missense variants affect phenotypes and how remains a challenge. (springer.com)
We investigate the functional relevance of de novo missense variants, specifically whether they are likely to disrupt protein interactions, and nominate novel genes in risk for ASD through integrated genomic, transcriptomic, and proteomic analyses. (springer.com)
Utilizing our previous interactome perturbation predictor, we identify a set of missense variants that are likely disruptive to protein-protein interactions. (springer.com)
Extending earlier work, we show that de novo missense variants that disrupt protein interactions are enriched in individuals with ASD, often affecting hub proteins and disrupting hub interactions. (springer.com)
The evidence, however, largely comes from protein-truncating variants (PTVs) as opposed to de novo missense (dnMis) variants. (springer.com)
These missense variants are uncommon, 8.3% of all missense variants given a score. (springer.com)
However, classification of missense variants often presents a difficult problem. (xenbase.org)
RESULTS: In the present analysis we were able to classify an additional 50 missense variants and two in-frame deletions as probably deleterious and 92 missense variants as probably neutral. (xenbase.org)
Thus we have tentatively classified about 50% of the unclassified missense variants observed during clinical testing of BRCA1 . (xenbase.org)

however, the role of TTN missense variants in DCM has been difficult to elucidate because of the presence of background TTN variation. (units.it)
Of the 348 missense variants, we identified 44 "severe" rare variants by using a bioinformatic filtering process in 37 probands. (units.it)
CONCLUSIONS--TTN missense variants are common and present a challenge for bioinformatic classification, especially when informative families are not available. (units.it)
Although DCM patients carrying bioinformatically "severe" TTN variants do not appear to have a worse clinical course than noncarriers, the nonrandom distribution of "likely" and "possibly" disease-causing variants suggests a potential biological role for some TTN missense variants. (units.it)
This report thus expands the spectrum of disease-causing variants in the KAT6A gene to also include missense variants in this gene. (centogene.com)
