Nonsynonymous mutations have a much greater effect on an individual than a synonymous mutation. In a nonsynonymous mutation, there is usually an insertion or deletion of a single nucleotide in the sequence during transcription when the messenger RNA is copying the DNA. This single missing or added ...

synonymous mutation, with ω=1. If the amino acid change is deleterious, purifying selection (Box 1) will reduce its fixation rate, thus ω<1. Only when the amino acid change offers a selective advantage is it fixed at a higher rate than a synonymous mutation, with ω>1. Therefore, an...
c A schematic diagram showing the definition of mutation to mouse. The phylogenetic tree is unscaled. d Fractions of SNPs that the reference allele is observed in monkey and the alternative allele is observed in mouse. P-value was calculated using Fisher's exact test. "onco" denotes cancer-...
This is relevant for the definition of Open Reading Frames. A generic case is provided by pseudo-random sequences, especially when they code for complex proteins or when they are non-coding and not subject to selection pressure. Here, we calculate, for such sequences and for all 25 known ...
ACCORDING to the neutral mutation–random drift hypothesis of molecular evolution and polymorphism1,2, most mutant substitutions detected through comparative studies of homologous proteins (and the nucleotide sequences) are the results of random fixation of selectively neutral or nearly neutral mutations. ...
As the codon mutation matrix was built from vertebrate DNA, its usable range is for the vertebrates and may be extendable to other metazoans. Tests with plants, yeasts and bacteria have so far not been successful, although muta- tion matrices more specific to specific species sets are under ...
Of these, the non-synonymous set is the most biophysically apparent - nsSNPs, by definition, alter the product protein sequence. However, since even these mutants do not necessarily have functional/structural consequences, the evaluation of the extent of their influence is non-trivial.; NsSNPs ...

variation interpretation; synonymous variation; mutation; terminology; variation naming; annotation1. Introduction Terminology in genetics is very important for precise transfer of information. Still, it is common to use confusing and even wrong terms, e.g., for variant types [1]. Variation Ontology...
