The huntingtin gene, also called the HTT or HD (Huntington disease) gene, is the IT15 ("interesting transcript 15") gene, which codes for a protein called the huntingtin protein. The gene and its product are under heavy investigation as part of Huntington's disease clinical research and the suggested role for huntingtin in long-term memory storage.
It is variable in its structure, as the many polymorphisms of the gene can lead to variable numbers of glutamine residues present in the protein. In its wild-type (normal) form, it contains 6-35 glutamine residues. However, in individuals affected by Huntington's disease (an autosomal dominant genetic disorder), it contains more than 36 glutamine residues (highest reported repeat length is about 250). Its commonly used name is derived from this disease; previously, the IT15 label was commonly used.
The mass of huntingtin protein is dependent largely on the number of glutamine residues it has, the predicted mass is around 350 kDa. Normal huntingtin is generally accepted to be 3144 amino acids in size. The exact function of this protein is not known, but it plays an important role in nerve cells. Within cells, huntingtin may be involved in signaling, transporting materials, binding proteins and other structures, and protecting against programmed cell death (apoptosis). The huntingtin protein is required for normal development before birth. It is expressed in many tissues in the body, with the highest levels of expression seen in the brain.
A gene is a locus (or region) of DNA that encodes a functional RNA or protein product, and is the molecular unit of heredity. The transmission of genes to an organism's offspring is the basis of the inheritance of phenotypic traits. Most biological traits are under the influence of polygenes (many different genes) as well as the gene–environment interactions. Some genetic traits are instantly visible, such as eye colour or number of limbs, and some are not, such as blood type, risk for specific diseases, or the thousands of basic biochemical processes that comprise life.
Genes can acquire mutations in their sequence, leading to different variants, known as alleles, in the population. These alleles encode slightly different versions of a protein, which cause different phenotype traits. Colloquial usage of the term "having a gene" (e.g., "good genes," "hair colour gene") typically refers to having a different allele of the gene. Genes evolve due to natural selection or survival of the fittest of the alleles.
Eugene is a common (masculine) first name that comes from the Greek εὐγενής (eugenēs), "noble", literally "well-born", from εὖ (eu), "well" and γένος (genos), "race, stock, kin".Gene is a common shortened form. The feminine variant is Eugenia or Eugénie.

Gene is a thriller novel by Stel Pavlou (born 1970), published in 2005 in England by Simon & Schuster. It is published in several languages with some title changes. The Italian edition has the title La Conspirazione del Minotauro (The Minotaur Conspiracy). The novel is about a fictional New York detective, James North, who in the process of hunting down a criminal, uncovers a genetics experiment to unlock past lives through genetic memory, therefore achieving a kind of immortality. In so doing North discovers his own origins, that of a soldier from the Trojan War who is reincarnated seven times through history, forced to confront his nemesis each time, all for the loss of his one true love.
