Gene Linked To Asthma In Blacks Discovered
Prior studies looking for asthma genes have turned up several, but most of the studies have been too small to confirm these genes or to detect genetic changes unique to different races.
The new study, published on Sunday in the journal Nature Genetics, pools research from nine different research groups looking for genes associated with asthma among ethnically diverse North American populations.
It confirmed four genes that had been seen in previous studies and a fifth that shows up only in people of African descent.
“This is the first discovery of a gene where we see a signal in African Americans only,” Dan Nicolae of the University of Chicago, a study author and co-chair of a national research consortium called EVE that identified the gene, said in a telephone interview.
