Gay gene
|
|
Gay geneA gene located on the X chromosome which was alleged to determine male homosexuality. The "gay gene" was dubbed homosexuality 1 (HMS1) and the male sexual orientation gene. It was thought to be in chromosome band Xq28. However, one would expect there to be strong selective pressures against a gene for male homosexual orientation. The original claim for the "gay gene" was made in 1993 by Dean H. Hamer and colleagues. There has been no independent confirmation of the existence of a "gay gene" and today there is considerable doubt about its existence.
RELATED TERMS--------------------------------------
Gene
1. A unit of DNA that carries information for the biosynthesis of a specific product in the cell. 2. Ultimate unit by which inheritable characteristics are transmitted to succeeding generations in all living organisms. Genes are contained by, and arranged along the length of, the chromosome. The gene is composed of deoxyribonucleic acid (DNA). Each chromosome of each species has a definite number and arrangement of genes, which govern both the structure and metabolic functions of the cells and thus of the entire organism.
Chromosome
A structural unit within a eukaryotic nucleus that carries genes. A chromosome consists of a long, continuous strand of DNA and associated proteins.
Homosexuality
Erotosexual pairing with a partner of the same genital morphology. Its full manifestation includes falling in love (homophilic limerence). Homosexual sexuoerotic behaviors may occur in same sex concentrations (as in prisons) from sexual frustration, or the expression of position in the heirarchy of dominance and power, for example (heterophlic homosexuality).
Sexual
Pertaining to sex or, more particularly, the stimulation, responsiveness, and functions of the sex organs either alone or with one or more partners.
Orientation
Awareness of one's self in relation to time, place, and person.
Homosexual
Characterized by same-sex contact, either as a genital act or as a long-term sexuoerotic status [from Greek, homos, same + sex]. It is analogous to left-handedness in being not pathological in itself, though not conforming to the statistical nor the ideological norm, and not being exempt from other pathology. A homosexual person is able to fall in love with, and become the pairbonded sexuoerotic partner of only a person of the same morphologic sex (homophilic homosexual). Homosexuality is not a paraphilia but a gender transposition, variable in extent and degree. Paraphilias may occur in association with either homosexual or heterosexual pairing.
Today
Today is a prescription or over-the-counter drug which is (or once was) approved in the United States and possibly in other countries. Active ingredient(s): nonoxynol-9.
SIMILAR TERMS--------------------------------------
Gay dating
In sexology, dating activity between same sex potential partners for sex intercourse.
Gay man
In sexology, street term for a male homosexual.
Gay porn
In sexology, the category of pornographic material specifically addressed to the gay community.
Gay sex
Sex intercourse between same sex partners.
Gay suicide risk
High rates of suicide have consistently been reported among homosexuals, particularly among adolescents and young adults.

Gastroscope
A flexible, lighted instrument that is put through the mouth and down the esophagus to view the stomach. Tissue from the stomach can also be removed through the gastroscope.
Gastrostomy, percutaneous endoscopic (PEG)
A surgical procedure for placing a feeding tube without having to perform an open laparotomy (operation on the abdomen). The aim of PEG is to feed those who cannot swallow. PEG may be done by a surgeon, otolaryngologist (ENT specialist) or gastroenterologist (GI specialist). It is done in a. hospital or outpatient surgical facility. Local anesthesia (usually lidocaine or another spray) is used to anesthetize the throat. An endoscope (a flexible, lighted instrument) is passed through the mouth, throat and esophagus to the stomach. The surgeon then makes a small incision (cut) in the skin of the abdomen and pushes an intravenous cannula (an IV tube) through the skin into the stomach and sutures (ties) it in place. The patient can usually go home the same day or the next morning. Possible complications include wound infection (as in any kind of surgery) and dislodging or malfunction of the tube. Percutaneous endoscopic gastrostomy may be a mouthful (as a term) but it describes the procedure accurately. A gastrostomy (a surgical opening into the stomach) is made percutaneously (through the skin) using an endoscope to put the feeding tube in place. PEG takes less time, carries less risk and costs less than a classic surgical gastrostomy which requires opening the abdomen.
Gaucher disease
A series of 5 diseases due to deficient activity of the enzyme glucocerebrosidase, leading to accumulation of glucocerebroside in tissues of the body. The 5 types of Gaucher disease encompass a continuum of clinical findings from a lethal form before or just after birth to a form so mild that it may not be diagnosed until old age. All 5 types of Gaucher disease are inherited in an autosomal recessive manner.
Gaucher disease, type 1
The most common and best known form of Gaucher disease. It affects the spleen, liver, and bone marrow and spares the brain. The symptoms include enlargement of the spleen (usually the first sign), anemia, low blood platelets, increased skin pigmentation, and a yellow fatty spot on the white of the eye (a pinguecula). Severe bone involvement can lead to pain and collapse of the bone of the hips, shoulders, and spine.
Gaucher disease, types 2-5
A series of disease due to glucocerebrosidase deficiency and accumulation of glucocerebroside in cells. By comparison with type 1 Gaucher disease, these are far less frequent forms of Gaucher disease.

High rates of suicide have consistently been reported among homosexuals, particularly among adolescents and young adults.
GB virus C
A virus related to the hepatitis C virus but which does not cause hepatitis and, in fact, is not known to be responsible for any disease. Infection with GB virus C (GBV-C) is beneficial to HIV-infected patients. They enjoy longer survival if they are coinfected with this virus and HIV than if they have HIV alone. Having two viruses is better than one here. Having both HIV and GB virus C is better than having HIV alone. GB virus C (GBV-C) is also called hepatitis G. However, the designation GB virus C (GBV-C) is preferred because the virus is not a cause of hepatitis.
GBV-C
GB virus C is genetically related to the hepatitis C virus but which does not cause hepatitis and, in fact, is not known to be responsible for any disease. Infection with GB virus C (GBV-C) seems to be beneficial to HIV-infected patients. They enjoy longer survival if they are coinfected with this virus and HIV than if they have HIV alone. GB virus C (GBV-C) is also called hepatitis G. However, the designation GB virus C (GBV-C) is preferred because the virus is not a cause of hepatitis.
GDF-8
The gene encoding growth and differentiation factor, also known as myostatin.
Gefitinib
A drug that attaches to the epidermal growth factor receptor (EGFR) on the surfaces of cells. The drug was designed to treat non-small-cell lung cancer. Marketed under the brand name Iressa.
