Study identifies 50 new genes that play a role in eye color compared to the two previously reported

More than meets the eye! A study identifies 50 new genes that play a role in journal coloration compared to the one or two previously reported to determine different shapes.

  • A study has identified 50 new genes involved in determining human eye color
  • The researcher performed the analysis with approximately 195,000 Europeans and Asians
  • It was previously believed that only one or two genes were involved
  • However, many of the new genes have not been reported to determine eye color









A new study reveals that human eye color is much more complex than previously believed.

A group of international scientists has identified 50 new genes involved in eye color following the genetic study of nearly 195,000 people in Europe and Asia.

It has previously been said that shadows were controlled by one or two genes, with brown eyes usually dominating blue.

The team also found 1,636 Asian participants with different shapes of brown eyes with European-like magazine pigmentation changes that have a wider range from dark brown to light blue.

‘The results of our study show that the genetic complexity of human eye color significantly exceeds previous knowledge and expectations, illuminating eye color as a very complex human attraction,’ read the study published in Science Advances.

The study, led by King’s College London and Erasmus University Rotterdam Medical Center, is considered to be ‘the largest genetic study of its kind to date.’

Co-author Dr Manfred Kayser, Medical Center of Erasmus University Rotterdam, said: ‘This study delivers the genetic knowledge needed to develop eye color prediction from DNA as applied as- is in anthropological and forensic studies, but with limited precision for non – brown and non – blue eye colors. ‘

The 50 new genes were previously identified, but were not classified as part of eye color.

For example, the team found that eight of the genes have been reported for genetic associations with other pigment markers, such as hair and skin color.

These findings will help develop an understanding of eye diseases such as pigmentary glaucoma and ocular albinism, where eye pigment levels play a role

‘In addition, we identified 34 genetic loci that were strongly associated with eye color, but are not reported to be significantly associated with hair and / or skin color,’ say researchers.

These findings will help develop an understanding of eye diseases such as pigmentary glaucoma and ocular albinism, where eye pigment levels play a role.

Co-author Dr Pirro Hysi, King, said: ‘The findings are encouraging because they take us one step closer to understanding the genes that cause one of the most influential traits in human faces, which have revealed mysterious generations throughout our history. ”

‘This will improve our understanding of many known diseases associated with particular levels of color.’

The color of our eyes has always been a mysterious wonder and is usually a wonder at birth.

However, new technologies allow people to choose a child’s eye shadow, along with other capabilities and features.

A type of gene modification called CRISPR is already being used by scientists in China to alter genetic mutations that cause disease in human embryos.

And a 2018 study showed that 39 percent of people change the DNA of their unborn baby to choose the color of their eyes.

FINALLY BLACK

About one in 20 people suffer from color blindness, a condition that makes the world a more likely place to look.

According to the NHS, it affects 1 in 200 women worldwide and 1 in 12 men.

There are four types of color blindness called protanopia, dueteranopia, tritanopia and achromatopsia.

Protanopia

Protanopia involves defective or absent wave cones in the retina; these photoreceptor cones are responsible for seeing red light. Defenders find it difficult to distinguish between red and green colors, and also between blue and green.

Deuteranopia

Deuteranopia is a condition where the photoreceptor green cone is missing from the retina. As a result, it is much more difficult for deutans to distinguish between green from red, as well as some green, purple and blue-green. Along with protanopia this is one of the most common color forms.

Tritanopia

Tritanopia is a complete absence of the short-wave cones in the retina that receive blue light. People with this very rare color type confuse light blues with grays, dark purples with black, medium green with blues and oranges with red.

Achromatopsia

People with complete acromatopsia cannot see any colors and can only see the world in black and white and dark gray.

There are two types of cells sensitive to the retina of the eye; rods and cones.

Both can be found in the image-processing cover at the back of your eye.

Rods work in low light conditions, but cones work in daylight and are responsible for color. People with color blindness have a problem with the cones in their retina.
