Heart at­tack gene may help you have a baby

The Daily Telegraph - - News -

Heart dis­ease may never be erad­i­cated be­cause it as­sists re­pro­duc­tion, a study by sci­en­tists at the Univer­sity of Mel­bourne has sug­gested.

Nat­u­ral se­lec­tion tends to weed out “bad” genes that re­duce sur­vival. Yet ge­netic vari­ants that in­crease the risk of heart dis­ease ap­pear to have been present in hu­man DNA at least as far back as the an­cient Egyp­tians.

Now sci­en­tists say the de­fects that fur up ar­ter­ies and lead to heart at­tacks may also im­prove fer­til­ity.

Re­searcher Dr Michael Inouye said: “We found CAD genes are also im­por­tant for re­pro­duc­tion and that these genes are in­volved in im­por­tant func­tions in male and fe­male fer­til­ity.”
