We are mainly surrounded by people with the usual eye color : gray, brown, blue, blue. To create a certain shade of eyes or just to emphasize their individuality, individual individuals use lenses of different colors. But some do not need to do this at all, since their eyes are of a rare color by nature. It is usually purple. Such a phenomenon is called the "origin of Alexandria."
Genetic mutationIn some babies, a change occurs 6-10 months after birth, as a result of which their eyes acquire a rare purple hue. This does not affect a person’s eyesight, but there is an opinion that people with purple eyes have a tendency to cardiovascular disease.
The mutation process lasts a long time and continues until puberty. At this time, the eyes become a darker shade that can even mix with blue. It remains only to understand how the "origin of Alexandria" is associated with genetic changes.
In the world there are many rare diseases that accompany a person all his life and have a genetic origin. The corresponding gene code is responsible for the color of the eyes , which also determines the shade of the hair and the presence of freckles. The Origin of Alexandria is one such rare anomaly.
Weil-Marchesani Syndrome
Sometimes this disease, which is hereditary, is called Weil-Marchezani syndrome. This pathology is also manifested by the following characteristic symptoms: short stature, a defect in the shape of the head and a change in the shape of the lens of the eye.
But the main sign of the “origin of Alexandria” mutation is purple eyes . In addition, people susceptible to this genetic disease have very developed muscles, thick fingers and a large layer of subcutaneous tissue. Many patients almost completely lack body hair, and women do not have a menstrual cycle, but at the same time they are quite capable of childbearing.
Albinos
It is generally accepted that albinos lack melanin in the iris, and therefore their eyes are red. But sometimes it can combine with blue, and the result is a purple hue. Such cases are extremely rare and are not related to the "origin of Alexandria" mutation.
Interesting information
Owners of violet eyes on the earth are very few. Therefore, when in 1329 a child was born with an unusual color of the iris, his parents turned to the priest for help, deciding that these were the machinations of Satan. But the church minister assured them that their child was not from the devil, but simply belonged to a special caste of people with rare purple eyes. The famous American actress Elizabeth Taylor had unusual violet-blue eyes that conquered her compatriots.
It is believed that pathology is transmitted through the mother and can be exacerbated from generation to generation. People with the genetic mutation “the origin of Alexandria” were credited with a longer life expectancy (up to 150 years), strong immunity and the inability to sunbathe in the sun.
Green eye color is also a fairly rare occurrence, it can boast only 2% of the total population of the planet. Pure black eyes and red, which are found in albinos, can be attributed to rare ones.
