Posted March 01, 2019 09:30:51It’s been a difficult few months for some newborns with a dark complexion.
But now researchers at the University of Melbourne have identified a new genetic variation that appears to protect against dark skin.
It was a mystery until researchers at Harvard University discovered that it was linked to a gene that produces the protein melanin.
Melanin helps the body to produce melanin pigments, a pigment that can help dark skin to appear darker.
“This is really the first time that we’ve found this variation that protects against dark-skinned infants,” senior author Dr Andrew Treglia told ABC News.
Dr Tregle told ABC’s RN Breakfast that the variation is unique to the family.
He said he had “never seen this before” in a newborn.
There were many genetic variations in the family, and they all play a role in skin tone.
The first person with this variation, which Dr Treglie described as a “small” variation, was found in Australia’s Northern Territory, and it was a common variant in Australian whites.
What causes dark skin colour?
Melansin plays a role to protect the skin from damaging UV rays and helps it to remain healthy, but it also plays a bigger role in the development of dark skin than any of the other genes that influence dark skin, Dr Trenlia said.
Vitamin D is a vitamin that helps protect the body from the sun and protects the skin, and the skin’s natural sunscreen, vitamin C, is also produced by melanin in the skin.
“We know that vitamin D helps protect against melanin, and melanin is involved in protecting against darkening skin colour, so we have this gene that protects from dark skin.”
The research team from the University’s School of Medicine and the University Centre for Genomic Medicine in Australia identified a mutation in a gene in the Australian Aboriginal population that was linked with darker skin.
They identified a gene called ALD2 which is a member of a family of genes that have been linked to melanin production in other parts of the body, including the eye, the brain, the liver and the pancreas.
They also found that the ALD1 gene was linked, in part, to melanoma.
Researchers have found melanoma genes that are involved in dark skin The gene that produced melanin melanoma is not present in white Europeans.
The team from Harvard University also discovered that there were other genes linked to dark skin that did not seem to play a part in dark-skin protection.
Their study was published in Nature Genetics.
Melanoma gene found in Australian Aboriginal populationsWhat can dark skin look like?
“What it means is that dark skin can develop at an early age and the melanocytes that are produced by these melanocytes are not mature enough to form melanin pigment,” Dr Trewhella said.
“What this means is, if we don’t produce the melanin to protect ourselves against melanoma, then we will eventually develop melanoma and we won’t be able to have dark skin until the melanoma has developed.”
Melanocytes in dark tissue are produced in the eyes, skin, brain and liver.
When the body needs vitamin D, it can make these cells more active and produce more melanin cells.
The new gene also appears to produce more of the vitamin than the ALI2 gene.
Other researchers are studying genes that appear to be involved in the melanocyte development process in the human body.
The Australian Aboriginal people are thought to have the strongest association with dark skin among Europeans.
Melansins are found in all human skin and can be produced by all the different types of melanocytes in the body.
Melanesin gene in Australians and Europeans is linked to darker skinThe researchers found that they also found a gene known as ALD3, which is not found in whites, but is associated with dark- skin in Europeans.
“This suggests that this gene may also be a factor in dark pigmentation,” Dr Kari Trenli said.
She said melanin was produced by skin melanocytes, which are the most active cells in the developing skin.
Dr Trenilia said that the genetic variation found in Australians, who are white, may have been found in other people in other regions of the world.
We have to find out how it came to Australia.
She said researchers would need to examine other populations in order to determine if it was something other than just the Australian population.
What is dark skin pigment?
There are three main types of pigment in the world, called melanin or melanocytes.
Each melanocyte produces a different pigment.
If you have a gene linked to light-sensitive skin pigmentation, for example, you will have a mixture of melanin and other pigment in your skin.Melanic
