EYCL2A gene for brown eye color.
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.
SIMILAR TERMS--------------------------------------
EYCL1
A gene for green/blue eye color located on chromosome 19.
EYCL3
A gene for brown/blue eye color located on chromosome 15.
PREVIOUS AND NEXT TERMS--------------------------------------
Extubate
To remove a tube from a hollow organ or passageway, often from the airway. The opposite of extubate is intubate.
Extubation
The process of removing a tube from a hollow organ or passageway, often from the airway. The opposite of extubation is intubation.
Exudate
A fluid rich in protein and cellular elements that oozes out of blood vessels due to inflammation and is deposited in nearby tissues. The altered permeability of blood vessels permits the passage of large molecules and solid matter through their walls.
Exudative angina
This has nothing whatsoever to do with the usual type of angina (angina pectoris) which is chest pain of cardiac origin. Angina trachealis is more commonly known as croup. This is an infection of the larynx, trachea, and the bronchial tubes, that occurs mainly in children. It is usually caused by viruses, less often by bacteria. Symptoms include a cough that sounds like a barking seal and a harsh crowing sound during inhaling.
EYCL1
A gene for green/blue eye color located on chromosome 19.
EYCL2
EYCL3
A gene for brown/blue eye color located on chromosome 15.
Eye
The organ of sight. The eye has a number of components. These components include but are not limited to the cornea, iris, pupil, lens, retina, macula, optic nerve, choroid and vitreous.
Eye bank
A place to store corneas (the clear "front window" of the eye) for use in future keratoplasty (surgery to replace the cornea).
Eye bleed
Medically called a subconjunctival hemorrhage. A very common cause of a painless bloody eye usually first noticed by somebody else or by the person with it when they look in the mirror. The bleeding results from a break in a small blood vessel in the sclera, the white of the eye. This releases a tiny amount (less than a drop) of blood which is trapped underneath the conjunctiva, much like the blood in a bruise is trapped in the skin. It is called a subconjunctival hemorrhage since it occurs beneath the conjunctiva, the transparent membrane covering the sclera.
Eye cataract
A clouding of the lens of the eye. The normally clear aspirin-sized lens of the eye starts to become cloudy. The result is much like smearing grease over the lens of a camera. It impairs normal vision.
