I think they didnt find a specific gene yet, only gene markers suggesting there mite be some kind of genetic disposition to develop homosexuality.
But in addition to homosexuality being purely genetic, there is a possibility it mite be some kind of development "dysfunction" that causes it (hormone levels altered during the sexual development of the brain in the fetus, causing a "female" sexual part of the brain in a male fetus and vice versa).
So people could still be born being homosexual, thus being predetermined to become homosexual, it's just not necessarily genetic.
