Dr. Vergano specializes in medical genetics and its influences on patients. One of her specific interests involves Coffin-Siris syndrome.

Dr. Vergano began studying Coffin-Siris syndrome (CSS) while completing her fellowship in medical genetics at the Children’s Hospital of Philadelphia.  She has continued her involvement with the CSS community upon her arrival at CHKD in 2012.

In 2015, the first international IRB-approved Coffin-Siris registry was begun and presently has over 90 individuals enrolled. Dr. Vergano has been active in the Coffin-Siris syndrome parent support group, attending annual CSS family meetings in Norfolk in 2016 and in Seattle in 2017. She finds working with this CSS community extremely rewarding and enjoys being able to help coordinate the often complex medical issues that arise for children with CSS.

Dr. Vergano is married to Dr. Scott Vergano of Pediatric Specialists. Together they have a daughter, Norma.
