Scientists have discovered how mutations in DNA can cause neurodegenerative disease. The discovery is an important step towards better treatment to slow the progression or delay onset in a range of incurable diseases such as Huntington's and motor neurone disease – possibly through the use, in new...
In a study of mice, the researchers found that mutations in Foxp2 disrupt the formation of dendrites and neuronal synapses in the brain's striatum, which play important roles in the control of movement. Mice with these mutations also showed impairments in their ability to produce the high-frequ...
which “may increase the risk for transmission to humans”. They conclude, “although the chance that such mutations will arise in an infected animal is very small, the impact of the emergence of a zoonotic virus with potentially pandemic characteristics may be large”. ...
Scientists can spot mutations faster than they can make sense of them. Many mutations will have no consequence for the virus’s ability to spread or cause disease, because they do not alter the shape of a protein. Scientists have claimed that a steady trickle of immune-evading mutations could...
Somatic mutations are mutated cells that are passed through cell division, often eventually becoming cancerous. Learn why somatic mutations occur and review a case study demonstrating how they can progress into dangerous cancers. Somatic Mutations The cells that make up your body, just about all of...

Instead, the investigators discovered that protein mutations linked to drug resistance often arise far from the drug’s target location. These mutations involve alterations that change the movements of a viral protein, or enzyme, that allows the virus to replicate itself. This raises the possibility...

The impact of protonation state on protein activity can arise from alterations to amino acids or their titration. Indeed, many cancer-initiating mutations influence pH balance, regulation or sensing in a manner that enables growth and invasion outside normal constraints as part of oncogenic ...
