The title and two places in the article require important corrections to the name of the genetic polymorphism under study to remedy errors that were introduced in typesetting. The first three pages that contain these errors are reprinted here to replace and correct those of the article. The correct title is “Diurnal cortisol rhythms in youth from risky families: Effects of cumulative risk exposure and variation in the serotonin transporter gene-linked polymorphic region (5-HTTLPR).”

These same changes are at the first citation of the term in the abstract on the first page on the third line: “. . . effect of environmental risk is moderated by allelic variation in the promoter region of the serotonin transporter gene-linked polymorphic region (5-HTTLPR). Results show that youth . . .” and on the third page in the third line of the second column paragraph beginning “One genetic marker . . .:” “. . . stressors is a variable length polymorphism in the promoter region of the serotonin transporter (5-HTT) gene, SLC6A4. This polymorphic region, termed 5-HTTLPR, displays short and long allelic variants, with the short allele . . .”

We sincerely regret these errors and any problems or misunderstandings they may have caused.
