However, this particular mutation was felt to be a false positive result, and further investigations identified a more likely mutation candidate (MLL2).
Since neither of these key tumor suppressors impede cell cycle progression in Lmna−/− cells, it is more likely that mutations inactivating A-type lamin function also contribute to tumorigenesis.
During natural selection, transitions are better tolerated because they generate more likely synonymous mutations in protein-coding sequences than transversions.
More likely, these mutations bring about changes in protein protein interactions, changes in localization of diguanylate cyclases in the cell, or alterations in the relative orientation of domains.
Essentially, stronger predictions are also more reliable, i.e. the higher the score, the more likely the mutation impacts function [ 19, 21, 22].
Based on his own findings of a loss of ribosomal RNA gene copies in postmitotic tissues of dogs as well as humans during aging, his main conclusion was that deletional mutations are more likely than point mutations to be a main causal factor in aging.
As stop-codon and nonsynonymous mutations are much more likely than synonymous mutations to substantially impair viral fitness, these results are consistent with purifying selection purging deleterious mutations during viral growth.
Because ORF2 itself is not under any selection, the above phenomenon must be due to the fact that synonymous mutations to ORF2 are more likely than nonsynonymous mutations to ORF2 to be deleterious to ORF1.
In addition, almost 80%% of highly expressed non-TE genes have insertion mutations, indicating that highly expressed genes in rice chromosomes are more likely to have mutations by mutagens such as T-DNA, Ds, dSpm and Tos17.
However, many of the mutations described in JEB cases are nonsense mutations near the amino-terminus, which are more likely than the mutation described herein to cause a complete knockout of the gene.
Jews are more likely to carry mutations for Tay-Sachs, Africans for sickle cell anemia.
