Summitt, 59, had coached the Tennessee women's team since 1974 and compiled a record of 1,098 wins and 208 losses. Her Tennessee Lady Vols teams won eight national championships.
Summitt announced last August that she had been diagnosed with early-onset dementia, but said she would continue coaching.
Known for her fiery presence, Summitt gradually retreated from day-to-day coaching duties this season and was often seen at games sitting quietly and allowing Warlick to take the lead in coaching players from the bench.
She coached the U.S. women's Olympic team to a gold medal at the Los Angeles Olympics in 1984 and was elected to the Naismith Basketball Hall of Fame in 2000.
"Just like there will never be another John Wooden, there will never be another Pat Summitt," Tennessee Director of Athletics Dave Hart said in a statement, referring to Summitt as an icon on a par with Wooden, the legendary men's college coach at UCLA who died in 2010.
