Officers, Board Members, and Staff


Douglas Riegert-Johnson, MD
 Board Chairman

Douglas Riegert-Johnson is a consultant of gastroenterology and medical genomics at Mayo Clinic Florida.  Since starting there in 2008, he has been caring for patients with hereditary cancer syndromes with a talented and caring team of genomic counselors, nurses and physicians.  The group has now cared for more than 300 patients with familial adenomatous polyposis, Lynch syndrome, Peutz-Jeghers syndrome and other hereditary cancer syndromes.


His family is originally from the Birmingham area of Alabama.  He graduated in chemistry from Samford University and in medicine from the University of Alabama School of Medicine.  After medical school, Dr. Riegert-Johnson trained at the Mayo Clinic in Rochester, Minnesota.  There he was a medicine resident and chief medical resident and then gastroenterology fellow.  In the middle of his training at Mayo, he went to Baltimore for two years to train in medical genetics at Johns Hopkins Hospital.  He was one of the last fellows during Dr. McKusick’s tenure.

As a medical genetics fellow Dr. McKusick assigned him the project of further investigating Stiff Skin syndrome, a syndrome Dr. McKusick had described in the 1960s.  The original patients were found and reascertained, and new patients were identified.  Using this data and the samples taken, the phenotype of Stiff Skin syndrome was clarified and the cause was found to be mutations in the FBN1 gene.  Dr. McKusick also introduced Dr. Riegert-Johnson to Peutz-Jeghers syndrome.  Dr. McKusick was the second author with Dr. Jeghers on the New England Journal of Medicine paper describing the syndrome in 1949.


Dr. Riegert-Johnson continued on with Peutz-Jeghers syndrome at Mayo Clinic Rochester under the mentorship of Dr. Lisa Boardman.  Together they have completed several book chapters, manuscripts and created a web resource with NCBI on the topic of Peutz-Jeghers syndrome.


Since moving to Mayo Clinic Florida, Dr. Riegert-Johnson collaborated with Dr. Henry Lynch to identify a founder EPCAM mutation as the cause of Lynch syndrome in his “Family R.” Family R had been studied by Dr. Lynch since the 1970s but by 2010 the cause of Lynch syndrome in this family still had not been determined.  Identification of an EPCAM mutation as the cause of Lynch syndrome allowed family members to finally determine if they did or did not have Lynch syndrome.  Also, since moving to Mayo Clinic Florida Dr. Riegert-Johnson has collaborated with Meaghan Roberts, CGC in investigating Muir Torre syndrome. They published a scoring system for clinicians to determine which patients with sebaceous neoplasms should be tested for Muir Torre syndrome.


Dr. Douglas Riegert-Johnson has been married to Dr. Vanessa Riegert-Johnson since 2000.  The Drs. Riegert-Johnson have been blessed with three wonderful children.
