Leena Peltonen-Palotie (16 June 1952 – 11 March 2010) was a Finnish geneticist who contributed to the identification of 15 genes for Finnish heritage diseases, including arterial hypertension, schizophrenia, lactose intolerance, arthrosis and multiple sclerosis. She was considered one of the world's leading molecular geneticists.
Peltonen-Palotie was born in Helsinki, but moved to Oulu while she was just five years old. She graduated from the Finnish Co-educational Lycée of Oulu in 1971. Peltonen-Palotie received her license (Licentiate of Medicine) in 1976 and in 1978, presented her dissertation to graduate to Doctor of Science in Medicine from the University of Oulu.
Peltonen-Palotie worked at the National Public Health Institute of Finland 1987–1998. From 1998 to 2002 she helped found the UCLA Department of Human Genetics. She had a professorial position in the Academy of Finland since 2003. In April 2005 Peltonen-Palotie was employed in the University of Helsinki and the National Public Health Institute of Finland. She was also the project director in the EU project GenomEUtwin that was formed to define and characterize the genetic components in the background of different diseases. In 2004 she became a member of the Board of Directors of Orion Corporation, the largest Finnish pharmaceutical company. In September 2007, Peltonen-Palotie joined the Wellcome Trust Sanger Institute as the head of Human Genetics. She also headed research groups at the Broad Institute of MIT and Harvard University.
Peltonen-Palotie published over 500 research articles and almost 80 invited articles, and mentored over 70 PhD students in her career. In addition to many academic awards she received an honorary degree from the Faculty of Medicine at University of Uppsala on January 22, 2000 and the University of Joensuu. In 2006, Peltonen-Palotie was awarded the Belgian prize Prix van Gysel and the Swedish prize Stora Fernströmpriset. In 2009, she was awarded the honorary title of Academician of Science in Finland.
In 2004 the Finnish television show, Suuret suomalaiset, listed Peltonen-Palotie as 77th of the 100 greatest Finns of all time. On International Women's Day 2010, her achievements were honored in the form of a commemorative postage stamp issued by the Finnish Post.
The Leena Peltonen Prize for Excellence in Human Genetics is named in her honor.
