RISK FAC­TORED INTO GENES

Herald Sun - - NEWS - JILL POULSEN

RISK-tak­ing be­hav­iour is in our genes, Aus­tralian and in­ter­na­tional sci­en­tists have found.

Peo­ple who like tak­ing a risk — or even just tend to speed and drink too much — may have some of the genes that re­searchers, in­clud­ing some from the Univer­sity of Queens­land, have linked to risk-tak­ing be­hav­iour.

The sci­en­tists looked across the whole genome to find those re­gions linked to gen­eral risk tol­er­ance, ad­ven­tur­ous­ness and risky be­hav­iours around driv­ing, drink­ing, smok­ing and sex.

They found 99 re­gions of DNA linked to our gen­eral tol­er­ance of risk, 46 of which were also linked to at least one other risky be­hav­iour.

They also found ev­i­dence that these ar­eas of DNA were in­volved in brain re­gions with a role in de­ci­sion mak­ing.
