Microsoft Corp. said Zain Nadella, son of Chief Executive Officer Satya and his wife Anu, died Monday morning. He was 26 years old. As per the reports, Zain was born with cerebral palsy (A congenital disorder of movement, muscle tone or posture).

In an email to its staff, the software company said that Zain had passed away.  “Hold the family in your thoughts and prayers while giving them space to grieve privately”,  the mail read.

Last year, the Children’s Hospital, where Zain received much of his treatment, joined with the Nadellas to establish the  Zain Nadella Endowed Chair in Pediatric Neurosciences, as part of Seattle Children’s Center for Integrative Brain Research. 

“Zain will be remembered for his eclectic taste in music, his bright sunny smile and the immense joy he brought to his family and all those who loved him,” Jeff Sperring, CEO of Children’s Hospital, wrote in a message to his Board, which was shared with Microsoft executives.
