The gene for male-pattern baldness (androgen receptor) has traditionally been linked to the X chromosome which means mom passes it on to her sons. Now, two new independent studies published yesterday at the Nature Genetics identified association between hair loss and chromosome 20.
A genome-wide association study (GWAS) for male-pattern baldness, or androgenetic alopecia, identified a new association at chromosome 20p11.22, between the PAX1 and FOXA2 genes, and confirmed a previous association with the gene encoding the androgen receptor in the X. Tim Spector and colleagues found that 1 in 7 men carry both the chromosome X and chromosome …read more

It’s not exactly the secret of immortality, but scientists have discovered the nearest thing to the secret of a long life. It’s in your genes.
Or rather, it’s in the gene called FOXO3A or the so-called “long life gene”, which The Hawaii Lifespan Study found was associated with better health and a longer life. The team led by Drs. Bradley Wilcox followed 8,000 Japanese-American men who had regular health exams since the 1960s, where they found that men who lived an average 98 years – the longevity group – had similarities in their genotypes.
Men who carry one copy of the …read more
