The Evan Lee Ungerleider Fund is a restricted fund within NTSAD. The fund was established by Shari and Jeff Ungerleider in honor of their son, Evan, who succumbed to Tay-Sachs disease when he was four years old.

Throughout his life and in his memory, the fund's goal is to raise money for research, education, carrier testing, and family support services. It is hoped these efforts will help prevent the tragedy of Tay-Sachs and allied genetic diseases in other families.
