WASHINGTON (Reuters) - A rare genetic abnormality found in people in an insular Amish community protects them from heart disease, a discovery that could lead to new drugs to prevent heart ailments, U.S. researchers said on Thursday.
About 5 percent of Old Order Amish people in Pennsylvania's Lancaster County have only one working copy rather than the normal two of a gene that makes a protein that slows the breakdown of triglycerides, a type of fat that circulates in the blood, the researchers wrote in the journal Science.
"People who have the mutation all have low triglycerides," said Toni Pollin of the University of Maryland School of Medicine in Baltimore, who led the study
"This gives us clues that ultimately could develop future treatments."
Triglycerides naturally disappear more quickly in these people than in people without this gene mutation.
New drugs might target this gene, called APOC3, to decrease the amount of the protein it produces, Pollin said in an interview.
