Washington: People with short stature may actually be missing out on certain specific genes, a new study has revealed.New research sifted through the entire genome of thousands of human subjects to look for genetic variation associated with height.The results of the study suggested that excess number of uncommon genetic deletions is associated with short height of the people.Height is a highly heritable trait that is associated with variation in many different genes.“Despite tremendous recent progress in finding common genetic variants associated with height, thus far these variants only explain about 10 percent of the variation in adult height,” said senior study author, Dr. Joel N Hirschhorn, from Children’s Hospital Boston and the Broad Institute.“It has been estimated that about half of height variation could eventually be accounted for by the sorts of variants we’ve been looking at, so it is possible that other types of genetic variants, such as copy number variants (CNVs), may also contribute to the genetic variation in stature.”
