A germlinemutation is any detectable and heritable variation in the lineage of germ cell s. Mutation s in these cells are transmitted to offspring while those in somatic cells are not. This distinction is most important in animal s, where germ cells are distinct from somatic cells. However, in plant s, the reproductive cells in a particular flower will be derived from the same meristem as the cells in that flower and on the Plant stem stem leading to the flower, which is a different population of cells than those that give rise to the other flowers on the plant. microorganism Single celled organism s have no distinction between germline and somatic tissues. In animals, mutations are more likely to occur in sperm than in ova , because a larger number of cell divisions are involved in the production of sperm. ref http www.schizophreniaforum.org for curr Malaspina default.asp Schizophrenia Risk and the Paternal Germ Line ref See also Germline References references Category Germ cells genetics stub ... more details
orphan date August 2010 Interferons induce the formation of two transcriptional activators gamma activating factor GAF and interferon stimulated gamma factor 3 ISGF3 . A natural heterozygous germline STAT1 mutation associated with susceptibility to mycobacterial but not viral disease was found in two unrelated patients with unexplained mycobacterial disease. ref Dupuis S, Dargemont C, Fieschi C, et al. Impairment of mycobacterial but not viral immunity by a germline human STAT1 mutation. Science. 2001 293 5528 300 303. ref This mutation caused a loss of GAF and ISGF3 activation but was dominant for one cellular phenotype and recessive for the other. It impaired the nuclear accumulation of GAF but not of ISGF3 in cells stimulated by interferons, implying that the antimycobacterial but not the antiviral effects of human interferons are mediated by GAF. More recently, two patients have been identified with homozygous STAT 1 mutations who developed both post BCG vaccination disseminated disease and lethal viral infections. The mutations in these patients caused a complete lack of STAT 1 and resulted in a lack of formation of both GAF and ISGF3. ref Dupuis S, Jouanguy E, Al Hajjar S, et al.

Refimprove date July 2009 In biology and genetics , the germline of a mature or morphogenesis developing individual is the line sequence of germ cell s that have genetic material that may be passed to a child. For example, gamete s such as the spermatozoan sperm or the ovum egg , are part of the germline. So are the cells that divide to produce the gametes, called gametocyte s, the cells that produce those, called gametogonium gametogonia , and all the way back to the zygote , the cell from which the individual developed. Cells that are not in the germline are called somatic cell s. This refers to all of the cells of body apart from the gametes. If there is a mutation or other genetic change in the germline, it can be passed to offspring, but a change in a somatic cell will not be. Germline cells are immortal, in the sense that they have the potential to reproduce indefinitely. This is largely due to the activity of the enzyme known as telomerase . This enzyme extends the telomeres of the chromosome , preventing chromosome fusion s and other negative effects of shortened telomeres. Most somatic cells, by comparison, can only divide around 30 50 times due to the Hayflick limit . Certain somatic cells, known as stem cells , also express telomerase and are potentially immortal. ref Watt, F. M. and B. L. M. Hogan. 2000 Out of Eden Stem Cells and Their Niches Science 287 1427 1430 . ref Not all multicellular organisms differentiate cells into somatic and germ lines. Notably, plants have no germline cells separate from stem cells. Germline can refer to a lineage of cells spanning many generations of individuals for example, the germline that links any living individual to the hypothetical first eukaryote of about 2 billion years ago, from which all plants and animals common descent descend .

Refimprove date March 2011 In genetics , a missense mutation a type of nonsynonymous mutation is a point mutation in which a single nucleotide is changed, resulting in a codon that codes for a different amino acid mutations that change an amino acid to a stop codon are considered nonsense mutations , rather than missense mutations . This can render the resulting protein nonfunctional. Such mutations are responsible for diseases such as Epidermolysis bullosa , sickle cell disease , and Superoxide dismutase SOD1 mediated Amyotrophic lateral sclerosis ALS Harv Boill e 2006 p 39 . For example, in the most common variant of sickle cell disease, the 20th nucleotide of the gene for the beta chain of hemoglobin found on chromosome 11 is erroneously changed from the codon GAG for glutamic acid to GUG which codes valine , so the 6th amino acid is incorrectly substituted after the initial methionine amino acid is removed . ref http www.ncbi.nlm.nih.gov omim 141900 141900Variants0243 OMIM 141900.0243 ref Not all missense mutations lead to appreciable protein changes. An amino acid may be replaced by an amino acid of very similar chemical properties, in which case, the protein may still function normally this is termed a neutral, quiet , or conservative mutation. Alternatively, the amino acid substitution could occur in a region of the protein which does not significantly affect the protein secondary structure or function. When an amino acid may be encoded by more than one codon so called degenerate coding a mutation in a codon may not produce any change in translation this would be a synonymous mutation a form of silent mutation and not a missense mutation.

In other words, it is neutral with respect to natural selection . For example, some mutations in a DNA triplet or codon do not change which amino acid is introduced this is known as a synonymous substitution . Unless the mutation also has a Regulation of gene expression regulatory effect, synonymous substitutions are usually neutral. Some non synonymous mutations, i.e. mutations that do change the amino acid, are also neutral these neutral changes are often to a chemically similar amino acid that works just as well. Such mutations may spread through genetic drift neutral drift . Neutral mutations can accumulate over time due to genetic drift or genetic hitchhiking genetic draft .

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 drug lamivudine . 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

In genetics , a dynamic mutation is an unstable heritable element where the probability of mutation is a function of the number of copies of the mutation. That is, the replication product of a dynamic mutation has a different likelihood of mutation than its predecessor. These mutations, typically short sequences repeated many times, give rise to numerous known diseases including the Trinucleotide repeat disorders . Robert I. Richards and Grant R. Sutherland called these phenomena, in the framework of dynamical genetics , dynamic mutations. Triplet expansion is caused by slippage during DNA replication. Due to the repetitive nature of the DNA sequence in these regions loop out structures may form during DNA replication while maintaining complementary base paring between the parent strand and daughter strand being synthesized. If the loop out structure is formed from sequence on the daughter strand this will result in an increase in the number of repeats. However if the loop out structure is formed on the parent strand a decrease in the number of repeats occurs. It appears that expansion of these repeats is more common that reduction. Generally the larger the expansion the more likely they are to cause disease or increase the severity of disease. This property results in the characteristic of anticipation seen in trinucleotide repeat disorders. Anticipation describes the tendency of age of onset to decrease and severity of symptoms to increase through successive generations of an affected family due to the expansion of these repeats. Common features Most of these diseases have neurological symptoms.
