Jordan Feldstein, the brother of actor Jonah Hill and actress Beanie Feldstein, died as a result of a blood clot that originated in his leg, according to online records from the Los Angeles County Coroner’s Office.
The coroner’s office listed Feldstein’s first cause of death as a pulmonary thromboembolism, a pulmonary embolism resulting from a clot originating somewhere else in the body. His second cause of death was deep leg vein thrombosis, a blood clot.
Acute bronchopneumonia and obesity were listed as other significant causes in the death of Feldstein, a music talent manager who died at age 40 on Dec. 22, 2017.
The coroner’s office did not immediately respond to PEOPLE’s request for additional comment.
