Found, Curly Hair Causes

Trichohyalin has long been known as a gene that has several roles in the development of hair follicles. Australian scientists succeeded in identifying genes that affect human curly hair.

Researchers at the Queensland Institute of Medical Research (QIMR) found Trichohyalin is a major gene that creates curls. Their study appears in the latest edition of American Journal of Human Genetics.

Head of QIMR Genetic Epidemiology Laboratory and co-author of the study, Professor Nick Martin said that the variations in these genes determine the level of straightness or curliness hair.



A previous study in Japan, have found genetic variation for straight thick hair that is dominant in the Asian population.

Differences in the distribution and the FGFR2 gene have been identified years ago and believed to be part of the evolution of the Asian population following their divergence from European prehistory.

Martin and his colleague Dr Sarah Medland trying to find the same variations that cause curly hair of people of European descent. It is known that 45% of European people have straight hair, wavy hair 40% and 15% have curly hair. They also found that as many as 90% possibility of inherited trait.

In recent work, researchers at QIMR laboratories analyze data collected from a study of 5000 twins in Australia for more than 30 years.

"We have a huge amount of information about a variety of properties," says Martin.

People are asking whether the twins before their hair straight, wavy or curly. Then try to match lab report with a single nucleotide polymorphism 2.5 million (SNP) that have been mapped on their genetisme.

"This is a gene that has been known for more than 20 years and has been involved in the production of hair. Gene that has been long in his blanket around hair follicles," says Martin
