Deafness, the most common sensorineural hearing loss at all stages of life, occurs either independently or as part of ...

Mutations are changes in the molecular 'letters' that make up the DNA code, the blueprint for all living cells. Some of these changes can have little effect, but others can lead to diseases, including ...

Genetic disorders can occur due to mutations in one gene (monogenic), multiple genes (multifactorial inheritance), and mutation in one or more chromosomes. Point mutations are where one nucleotide in ...

Human cells usually contain two copies of most genes, one of which comes from the mother while the other comes from the father. It's long been thought that usually these two copies, or alleles of ...

Researchers have discovered new regions of the human genome particularly vulnerable to mutations. These altered stretches of DNA can be passed down to future generations and are important for how we ...

A man sits outside and holds a slim menthol cigarette between his fingers. Close-up with focus on the cigarette. The study provided a comprehensive examination of how lifestyle and environmental ...

What Is the MTHFR Gene Mutation? The MTHFR gene mutation is a variation in the MTHFR gene. This gene normally tells your body how to make the MTHFR protein. You need this protein to process folate, ...

In genomes, three letters or bases of DNA encode an amino acid. Amino acids are then strung together by the cell to create proteins. There is some redundancy in that genetic code, but there are single ...

Researchers are adding new evidence to the emerging concept that 'silent' or synonymous mutations may have crucial consequences. Their study showed how a synonymous mutation in one gene can ...
