Study Pinpoits Genome Markers that Predicts Male Sexual Orientation

A study at the School of Medicine of the University of California, Los Angeles, provides more bad news for the Christofascists and the bitter, closet old men at the Vatican.  These knuckle draggers - and in the case of the Vatican, proponents of 13th century knowledge - continue to whine and state that sexual orientation is a choice and make spittle flecked rants that there is "no gay gene."  Thus, being gay and having gay relationships is a "sin" in their ignorance embracing views.  The new study found that just  nine regions of the human genome predict the sexual orientation of males with up to 70 percent accuracy.  Obviously, none of us "chose" to change are DNA.  A press release outlines the findings that underscore that sexual orientation is NOT a choice.  Here are highlights:

An algorithm using epigenetic information from just nine regions of the human genome can predict the sexual orientation of males with up to 70 percent accuracy, according to research presented at the American Society of Human Genetics (ASHG) 2015 Annual Meeting in Baltimore.

"To our knowledge, this is the first example of a predictive model for sexual orientation based on molecular markers," said Tuck C. Ngun, PhD, first author on the study and a postdoctoral researcher at the David Geffen School of Medicine of the University of California, Los Angeles.

Beyond the genetic information contained in DNA, the researchers examined patterns of DNA methylation - a molecular modification to DNA that affects when and how strongly a gene is expressed - across the genome in pairs of identical male twins.

They found that methylation patterns in nine small regions, scattered across the genome, could be used to predict study participants' sexual orientation with 70 percent accuracy.

"Previous studies had identified broader regions of chromosomes that were involved in sexual orientation, but we were able to define these areas down to the base pair level with our approach," Dr. Ngun said. He noted that it will take additional research to explain how DNA methylation in those regions may be related to sexual orientation. The researchers are currently testing the algorithm's accuracy in a more general population of men.

"Sexual attraction is such a fundamental part of life, but it's not something we know a lot about at the genetic and molecular level. I hope that this research helps us understand ourselves better and why we are the way we are," Dr. Ngun said.
Ask any gay - or at least those not afflicted by religious brainwashing and associated guilt - and they will tell you that they never chose their sexual orientation.  To the extent there is any choice involved, it is merely the choice of how long one is willing to lie to themselves and others.
