These mutations can lead to severe protein destabilization and misfolding.
In extreme cases, highly deleterious mutations can lead to profound pathology.
Oxidative damage to DNA can cause mutations, and mutations can lead to cancer.
Second, some nonsense or frameshift mutations can lead to the complete absence of a protein.
Gene mutations can lead to genetic disease and cancer, but the rates of mutation are not uniform across the genome.
These mice reflect the situations in humans in which point mutations can lead to protein malfunction and disease development.
Frameshift mutations can lead to drastic loss of function and occur through the addition or deletion of one or more DNA bases.
Mutations can lead to strains that cause diarrhea by giving off toxins, invading the intestinal lining, or sticking to the intestinal wall.
Although genetic diversity increases the rate of adaptive evolution, low replication fidelity can present a risk because excess mutations can lead to population extinction.
The study, the first to follow heart-cell differentiation over time in such detail, could help scientists better understand how particular mutations can lead to congenital heart defects.
The Census reports a dominant missense mutation in TSHR that is associated with thyroid adenoma, and studies have shown that constitutive activation of TSHR by somatic mutations can lead to toxic thyroid adenoma43,44,45.
