Biography of Jon Morton Aase

Jon Morton Aase is reckoned as the pre-eminent authority on the foetal alcohol syndrome, the most common cause of mental deficiency. He was born in Wisconsin and grew up in California and Alabama.

After graduating in medicine from Yale University in New Haven, Connecticut, he interned at the University of Minnesota and completed his residency at the University of Washington. He then spent two years studying the indigenous population of Alaska, before he returned to Seattle to work with the paediatrician and dysmorphologist David W. Smith (1926-1981). After five more years in Alaska he came to the University of New Mexico, Albuquerque, where he became chief of the dysmorphology division.

Aase is the author or co-author of over forty-five articles in the area of dysmorphology. He developed the FAS Clinical Checklist and Screening Protocol for the Centers for Disease Control, and in early 2000 was conducting a Study of the Epidemiology of FAS in New Mexico for the Centers for Disease Control. He is on the advisory board of National Organization on Fetal Alcohol Syndrome. Besides his tenure at the University of New Mexico Aase (1996) is a consulting dysmorphologist in private practice. He also provides clinical and educational services for various state and national agencies.
