Scientists found 100 more genes associating human hair pigmentation, as until now only 24 genes were discovered that color the human hairs. The new findings revealed by the journal – Nature Genetics are very helpful for researchers to learn genetic complexity and also justify the variations of human pigmentation.
Researchers are hopefully expecting the new human hair pigmentation study to boost the perceptions for the conditions that are associated with different sorts of pigmentation like prostate, testicular, skin and ovarian cancers. All the 124 genes have a crucial function in assigning the specific colors to the hairs, according to the findings which may also guide the law enforcers to estimate the hair color of the criminal with the help of DNA evidence obtained from the crime scene.
Lead author of the study, Tim Spector, who is a professor at the King’s College London, says that, “We found that women have significantly fairer hair than men, which reflects how important cultural practices and sexual preferences are in shaping our genes and biology. This work will impact several fields of biology and medicine. As the largest ever genetic study on pigmentation, it will improve our understanding of diseases like melanoma, an aggressive form of skin cancer.”
During the study, a team of researchers from the Erasmus MC University Medical Center Rotterdam, Netherlands and King’s College London in the United Kingdom followed analyses of DNA samples of around 300,000 European descent residents and all the necessary details of their hair colors.
“Besides substantially increasing our understanding of human pigmentation genetics in general,” said Erasmus University’s Professor Manfred Kayser, study’s co-author, “finding these new hair color genes is also important for further increasing the accuracy of hair color prediction from DNA traces in future forensic applications, which can help to find unknown perpetrators of crime.”
