Activist Groups Urge Obama to Reject Boy Scout Honor
From Fox News:
Activist groups, including Scouting for All, urge President Obama not to accept the honorary Presidency of the Boy Scouts of America until they stop discriminating.

FOR IMMEDIATE RELEASE:
FIRST GENOME SCAN OF MALE SEXUAL ORIENTATION PUBLISHED
CHICAGO, Illinois, USA, January 12, 2005
A new genetic study helps explain why some men are gay and other men are heterosexual. The first
research project that examines linkage between male sexual orientation and genes across the human genome was published
this month in the prestigious biomedical journal, Human Genetics. The culmination of several years of research,
the report identified three new chromosomal regions of interest.
One hundred forty-six families that had two or more gay brothers participated in the study. The largest finding
was a statistically suggestive linkage to a region on chromosome 7 called 7q36, and the second largest link was
found on chromosome 8, in a region called 8p12. There was also an interesting finding on chromosome 10, in the
region called 10q26, where the linkage to sexual orientation only occurred if that region was
inherited from the mother. This is likely a result of the recently discovered phenomenon that geneticists call
'genomic imprinting.' Given the complex nature of sexual orientation it is not surprising that multiple genetic
regions were implicated.
According to the lead author of the study, Dr. Brian Mustanski, "Our study helps to establish that genes play
an important role in determining whether a man is gay or heterosexual. It expands upon previous research with twins,
which has consistently found evidence for genetic influences on sexual orientation. The next steps will be to see
if these findings hold up in a new sample and then identify the particular genes within these newly discovered
chromosomal regions." Dr. Mustanski emphasized that finding the specific genes would have implications beyond
uncovering the cause of homosexuality. Their identification would also greatly advance our understanding of human
variation, evolution, and brain development.
Previous genetic research had focused on the X-chromosome, which men inherit only from their mothers, because of
the tendency for homosexuality to pass through the mother's side of the family. When the scientists
used their new genetic markers, they confirmed linkage to the X chromosome in the previously studied families of
this sort, but not in new families with different patterns of inheritance. This pattern of findings suggests that
different genes may influence sexual orientation in different families, a process referred to as locus heterogeneity.
The study was conducted at the National Institutes of Health in the laboratory of the senior author, Dr. Dean
Hamer. Researchers in the laboratory of Dr. Nicholas Schork at the University of California at San Diego provided
statistical consultation on the project. Dr. Brian Mustanski is currently at the University of Illinois at Chicago.
The study was published in the online version of Human Genetics on January 12, 2005 and will be in print in an
upcoming issue of the journal.
