PM Lee offers condolences to Chan Soo Sen

Prime Minister Lee Hsien Loong with Mr Chan Soo Sen at the wake of Mr Chan's wife Patricia on Sunday.

Mrs Chan died last Thursday after suffering from a rare genetic disease that deprived her of sleep.

She found that she had inherited fatal familial insomnia through a test eight years ago, but her insomnia started in April this year after her 57th birthday.
