Sergey Brin Family Foundation — Parkinson's disease research
$150 million
donated to UCSF Parkinson's research program; cumulative through 2022
Motivated by his mother's Parkinson's diagnosis and the discovery that he carries a LRRK2 gene mutation associated with elevated Parkinson's risk, Brin donated $150 million to UCSF's Parkinson's research program — one of the largest single commitments in Parkinson's research history. The funding has supported dozens of researchers and several clinical trials.
