New "eye colour genes" discovered

New genes which have an impact on eye colour have been discovered, according to experts in the Netherlands.

The study, led by Manfred Kayser of the Erasmus University Medical Center Rotterdam and published in the open-access journal PLoS Genetics, reveals that three new genetic loci have been identified with involvement in subtle and quantitative variation of human eye colour.

According to the specialists, these three genes, together with previously identified ones, explain over 50 per cent of eye colour variance, representing the highest accuracy achieved so far in genomic prediction of complex and quantitative human traits.

"These findings are also of relevance for future forensic applications, where appearance prediction from biological material found at crime scenes may provide investigative leads to trace unknown persons," Mr Kayser said.

Meanwhile, Dr Kathryn Bollinger, a Medical College of Georgia clinician specialising in glaucoma, recently stated that an expression of a certain type of protein in glaucoma patients may enable more effective diagnosis of the condition.
