Palomaki reports that he has no personal conflicts of interest to disclose, but his employer has received project grants from Beckman Coulter, PerkinElmer and DSL. Jo Ellen S. Lee reports that she is a consultant for Genzyme Genetics. Jacob A. Canick reports that, with others, he hold patents on the use of unconjugated estriol in prenatal screening for Down syndrome and is a paid consultant to Beckman Coulter Inc. Geraldine A. McDowell declares no conflicts of interest. Alan E. Donnenfeld is an employee of Genzyme Genetics.
