An international research team has for the first time identified nine genes responsible for eyebrow colours.

Eyebrow colour is one of the most recognisable visual traits of the human body. It has a strong correlation with hair colour, but scientists believe in the existence of overlapping and unique genetic components for both traits.

Previous studies on human eyes, hair, and skin colour have identified multiple gene variants, but no findings for eyebrow colour have been reported as of yet.

For the new study, researchers from China, the Netherlands, Australia, Britain and the US analysed samples of 6,513 European individuals, and graded colours into four categories: red, blond, brown and black, Xinhua reported.

They found that eight genes, previously known pigmentation genes, could affect both eyebrow and hair colour, such as gene variant MC1R, responsible for both blond eyebrows and red hair.

In addition, C10orf11 is the newly-identified gene that only affects eyebrow colours.

With these findings, researchers developed an eyebrow colour prediction model and are ready to improve it by studying the different age distributions.

Such a DNA-based eyebrow colour prediction model would improve the human phenotype research and be useful in future forensic applications, said lead author Liu Fan, researcher at the Beijing Institute of Genomics of the Chinese Academy of Sciences.

“Based on the new discoveries, we can more accurately infer individual hair, eyes, skin, eyebrow colour and other phenotypic information just from a DNA sample,” Fan said in the paper published in the Journal of Investigative Dermatology.

Eyebrow colour is controlled by genes that affect production of pigment. Melanin, for example, is a protective pigment that can block the ultraviolet radiation. Melanin-related gene abnormalities can lead to many diseases, such as albinism, and increase the risk of skin cancer.

Therefore, an in-depth understanding of the pigmentation genes will help improve the treatment of these diseases, the researchers noted. (IANS)

To Ensure Transparency, WHO Panel Aims for Registry of All Human Gene-Editing Research

The WHO panel's statement said any human gene-editing work should be done for research only, should not be done in human clinical trials, and should be conducted transparently.

It would be irresponsible for any scientist to conduct human gene-editing studies in people, and a central registry of research plans should be set up to ensure transparency, World Health Organization experts said Tuesday.

After its first two-day meeting in Geneva, the WHO panel of gene-editing experts — which was established in December after a Chinese scientist said he had edited the genes of twin babies — said it had agreed on a framework for setting future standards.

It said a central registry of all human genome-editing research was needed “in order to create an open and transparent database of ongoing work,” and asked the WHO to start setting up such a registry immediately.

“The committee will develop essential tools and guidance for all those working on this new technology to ensure maximum benefit and minimal risk to human health,” Soumya Swamanathan, the WHO’s chief scientist, said in a statement.

A Chinese scientist last year claimed to have edited the genes of twin baby girls.

News of the births prompted global condemnation, in part because it raised the ethical specter of so-called “designer babies” — in which embryos can be genetically modified to produce children with desirable traits.

Top scientists and ethicists from seven countries called last week for a global moratorium on gene editing of human eggs, sperm or embryos that would result in such genetically-altered babies — saying this “could have permanent and possibly harmful effects on the species.”

The WHO panel’s statement said any human gene-editing work should be done for research only, should not be done in human clinical trials, and should be conducted transparently.

“It is irresponsible at this time for anyone to proceed with clinical applications of human germline genome editing.”

The WHO’s director-general, Tedros Adhanom Ghebreyesus, welcomed the panel’s initial plans. “Gene editing holds incredible promise for health, but it also poses some risks, both ethically and medically,” he said in a statement.

The committee said it aims over the next two years to produce “a comprehensive governance framework” for national, local and international authorities to ensure human genome-editing science progresses within agreed ethical boundaries. (VOA)
