Human Behavior Genetics

In the 1990s Hamer began studies of the role of genes in human behavior. In 1993 he published a paper suggesting the existence of gene
Gene
A gene is a molecular unit of heredity of a living organism. It is a name given to some stretches of DNA and RNA that code for a type of protein or for an RNA chain that has a function in the organism. Living beings depend on genes, as they specify all proteins and functional RNA chains...

Xq28
Xq28 is a genetic marker on the X chromosome found by Dean Hamer and others in 1993. Hamer's study led to his belief that they found a link between the Xq28 marker and male homosexuality, but the original study's results have been disputed.-1993 study:...

.
This finding was replicated in two studies in the United States but not in a third in Canada; meta-analysis indicated Xq28 has a significant but not exclusive effect.
Subsequently, several additional linked regions on other chromosomes have been described.

In 1996, Hamer and colleagues investigated the genetic roots of anxiety and found that the gene for the serotonin transporter, which is the target of antidepressant drugs such as Prozac, is partially responsible.
This polymorphism has been extensively replicated and its activity has been confirmed by direct brain imaging studies.
More recently, Hamer has postulated the existence of a God gene

Books

Hamer has published a number of popular science books that are aimed at a general readership and have been favorably reviewed in the New York Times, New York Review of Books, and Time magazine.

Films

Hamer turned to documentary filmmaking to address complex scientific and social issues often overlooked by the mainstream media. In 2005, he and his partner in life and filmmaking Joe Wilson, formed Qwaves with the mission of producing insightful and provocative films that "emanate from the voices of those on the outside, that incite us to abandon our comfortable role as spectators, and that compel us to question and to act." Their films have won numerous awards including winner of the PBS Independent Lens Shorts Festival, winner of the Videomaker National Documentary Film Challenge, and jury and audience awards and official selection at more than 100 film festivals worldwide. Qwaves films were part of the pioneering days of citizen-generated content on the Internet and cable television, and have been used as outreach and educational tools by a wide range of community and educational organizations.

OUT IN THE SILENCE, the first feature film from Qwaves, was supported by the Sundance Documentary Film Program and premiered at the Human Rights Watch International Film Festival at Lincoln Center to critical acclaim. It was broadcast on PBS

 for achievement in documentary. Through more than 500 grassroots screenings across the country, this film has become part of a national movement to open dialogue, counter school bullying, and support fairness and equality for all in small towns and rural communities.

In 2011, the OUT IN THE SILENCE YOUTH ACTIVISM AWARD was initiated to highlight the contributions of young people to achieving respect, inclusion and equality for lesbian, gay, bisexual and transgender people.

He was also featured in comedian Bill Maher's 2008 documentary "Religilous".
