Isabella Tate, a young actor who landed her first acting role in ABC’s 9-1-1 Nashville, died suddenly on Sunday. She was 23.

On Thursday, Tate’s talent agency, The McCray Agency, confirmed in an Instagram Story that she died from “a rare form of Charcot-Marie-Tooth disease.” She died “peacefully” on Oct. 19, and her family “requests privacy as they deal with this sudden and shocking loss.”

“CMT is a rare multisystem, multiorgan disease that causes lifelong, progressive symptoms, including muscle weakness and atrophy in the arms and legs, sensory loss, and other complications,” according to the Charcot-Marie-Tooth Association. “These symptoms often lead to challenges with balance, walking, hand use, and other daily activities.”

The McCray Agency also included a link to donate to the organization, saying, “In lieu of flowers, the family asks that donations in Izzy’s memory be made at the same link.”

‘We are deeply saddened and completely heartbroken’

Tate was born and raised in Nashville, Tennessee, and grew up in the Franklin community, according to an online obituary. She was a graduate of Middle Tennessee State University with a bachelor’s degree in business.

The McCray Agency also shared a loving tribute to Tate on Instagram, writing, in part, “We are deeply saddened and completely heartbroken to share that Isabelle Tate passed away on October 19th. She was 23.” The post’s caption mentioned, “I’ve known Izzy since she was a teenager and she recently returned to acting. She booked the first series she auditioned for, 9-1-1 Nashville. She had a wonderful time.”

What was Tate’s character on the show?

In the pilot episode of 9-1-1 Nashville, Tate played Julie, a wheelchair user who attended a strip show where Hunter McVey’s character, Blue, made her feel special.

McVey said he was “shocked” after learning of Tate’s death and offered “prayers for her family,” he told People in a statement.

“I didn’t know Isabelle prior to filming, but I couldn’t have asked for someone better to work with on one of my first-ever days on set,” he said.
