Genome and male sexual orientation

A recent discovery found that, the male sexual orientation is linked to a section of chromosome 13 near the gene SLITRK6 which is expressed in the diencephalon (brain region) that was previously found to vary in structure between gay and straight men, and the chromosome 14 near the gene for thyroid stimulating hormone receptor. This TSHR has previously been reported to have a link between homosexuality with atypical thyroid function. Some researchers however conclude that the sample size for this study was small to come up with the conclusion, and perhaps claim the only reason this would be big news would be due to the controversy with the topic. In the meantime, while other researchers try to expand this study and use more acceptable methods, we can appreciate this piece of news and fight about it later.
