A germline mutation is any detectable and heritable variation in the lineage of germ cell s. Mutation s in these cells are transmitted to offspring , while, on the other hand, those in somatic cells are not. A germline mutation gives rise to a constitutional mutation in the offspring, that is, a mutation that is present in virtually every cell. A constitutional mutation can also occur very soon after fertilisation , or continue from a previous constitutional mutation in a parent. ref http www.daisyfund.org rb about genetics.html RB1 Genetics at Daisy s Eye Cancer Fund. Retrieved May 2011 ref This distinction is most important in animal s, where germ cells are distinct from somatic cells.

The term resistance mutation is most commonly used to describe point mutation s in virus gene s that allow the virus to become resistant to treatment with a particular antiviral drug . The term is now being seen with more frequency in bacteriology and parasitology . The term resistance mutation first appeared in the management of HIV , which was the first virus in which genome sequencing is routinely used to look for drug resistance. Nomenclature Resistance mutations are conventionally listed as a letter, number and letter. For example, the M184V mutation in the reverse transcriptase gene of HIV confers resistance to the drugs lamivudine and emtricitabine. The letters stand for amino acid s and use the traditional one letter abbreviations. M stands for methionine , and V stands for valine 184 is the number of that amino acid position counting from the amino terminus of the protein. M184V means that the 184th amino acid of the protein is normally methionine, but that a mutation in the gene for that protein produces a form of the protein where that amino acid is substituted by valine instead. The form V184 is sometimes seen this means that the 184th amino acid of that protein is valine, but it gives no information as to whether that is a mutation or the normal state of affairs. The Greek capital letter delta indicates a deletion so M184 would mean that the 184th amino acid is usually methionine, but that this position is now missing. Alternatives are separated by slashes so, M184V I means either M184V, or M184I . References references Category Mutation Pharma stub Genetics stub virus stub ... more details
