Humans carry one to two lethal recessive mutations on average, study estimates Posted on April 8, 2015 by Kevin Jiang Humans carry on average one to two mutations that, if inherited from both parents, can cause severe genetic disorders or death before reaching reproductive age, report scientists from the University of Chicago and Columbia University.
Only one in about 400 women carry mutations to BRCA1 or to a related gene BRCA2, though such hereditary defects are implicated in between 5 percent and 10 percent of all breast cancers. The majority of the 230,000 cases of breast cancer diagnosed annually in the United States are not related to these genes.
