Trying to narrow the site of the mutation, gene mapper Hans Eiberg of the University of Copenhagen and colleagues examined members of a large Danish family, an approach that allowed them to follow DNA as it passed from one generation to another.

Vogelstein also argued that the new research about random mutations should offer comfort to people who develop cancer despite having «near - perfect lifestyles,» as well as to parents who are worried that they somehow «gave» their children cancer, either by passing on a harmful gene or inadvertently exposing them to an environmental toxin.

Between five and 10 % of all cancers are hereditary, which means that changes (or mutations) in specific genes are passed from one blood relative to another.

About 5 - 10 % of all cancers are inherited, meaning that mutations in specific genes are passed from one blood relative to another.

Familial cancer, also known as hereditary cancer is a condition caused by mutations in specific genes that is passed from parent to child.

Ironically, it's the mutations that make a plant less likely to survive and pass on its genes - softer seed husks, more flexible stems, tightly held bundles of grain - that make it more useful for cultivation.

Hereditary: Hereditary cancer is caused by abnormal, or mutated, genes that are passed down through generations within a family, causing family members who inherit the mutation to be diagnosed with certain types of cancers.

Now a trial has successfully repaired a disease - causing mutation in a human embryo, which would prevent that gene from being passed down to future generations.

To understand the selection mechanism behind mutations, network - based studies were used to estimate the importance of a mutated protein compared to non-mutated ones in signalling and protein — protein interaction networks.10, 11,12,13 Proteins mutated in cancer were found having a high number of interacting partners (i.e., a high degree of connectivity), which indicates high local importance.10 Mutated proteins are also often found in the centre of the network, in key global positions, as quantified by the number of shortest paths passing through them if all proteins are connected with each other (i.e., they have high betweenness centrality; hereafter called betweenness).11, 12 Mutated proteins also have high clustering coefficients, which means their neighbours are also neighbours of each other.10, 13 Moreover, neighbourhood analysis of mutated proteins have been previously successfully used to predict novel cancer - related genes.14, 15 However, to the best of our knowledge, no study has concentrated particularly on the topological importance of first neighbours of mutated proteins in cancer, and their usefulness as drug targets themselves.

The reason for all the types of mutations is variations in the specific genes passed on from each parent.

The most common forms of MTHFR mutation involve various combinations of these genes being passed on from each parent:

Research estimates that as much as half of the population may have an MTHFR gene mutation, though there are many variations of the mutation, depending on how the gene was passed down from the parents.

You can have one or two mutations on the 677 or the 1298 or you might have a mutation on both the 677 and 1298, depending on if one or both parents passed the gene onto you.
