50 whys to look for genes: 35. Find “missing heritability”

[G]enomic studies have had difficulty identifying causally relevant genetic variants behind variation in human traits (McCarthy et al. 2008, Couzin-Frankel 2010). Even when many genetic variants are examined together, only a small fraction of the variation in the trait is associated with—or in statistical terms, “accounted for” by—the genetic variants. This finding has led to discussions about missing heritability (e.g., Manolio et al. 2009)…

and bridging the gap by finding additional genetic variants (e.g., Wheeler and Barroso 2012). Continue reading
