Scientists have uncovered 1,559 genetic differences between males and females that relate not only to the sexual organs, but surprisingly to other organs such as the brain, skin, and heart.
“Overall, sex-specific genes are mainly expressed in the reproductive system, emphasizing the notable physiological distinction between men and women,” the scientists found. “However, scores of genes that are not known to directly associate with reproduction were also found to have sex-specific expression (e.g., the men-specific skin genes),” they added.
The findings suggest to the casual reader that there is much more involved in the notion of changing one’s gender to the opposite sex than simply surgery and hormonal treatment.
“Our results can facilitate the understanding of diverse biological characteristics in the context of [the male and female] sex,” the researchers stated in their conclusion.
The study, titled The landscape of sex-differential transcriptome and its consequent selection in human adults, was published in BMC Biology earlier this year.
In the study, researchers Moran Gershoni and Shmuel Pietrokovski of the Weizmann Institute’s Molecular Genetics Department mapped out thousands of genes — the biological databases of all the information that makes every person unique — from 53 tissues that are similar to males and females, such as the skin, muscle, and brain.
The study was conducted to examine the extent to which genes determine how certain diseases target males and females differently.
“Men and women differ in obvious and less obvious ways – for example, in the prevalence of certain diseases or reactions to drugs. How are these connected to one’s sex? Weizmann Institute of Science researchers recently uncovered thousands of human genes that are expressed – copied out to make proteins – differently in the two sexes,” a report from the Weizmann Institute about the findings stated.
