Baltacha battled the liver condition primary sclerosing cholangitis– an inflammation and scarring of the bile ducts – since the age of 19 and was diagnosed with liver cancer in January, two months after her retirement.
LTA’s head of women’s tennis Iain Bates said: “We have lost a shining light from the heart of British tennis, a true role model, a great competitor and a wonderful friend.
“We have so many special memories to cherish, but this leaves a gaping hole for everybody in both British and women’s tennis and words simply cannot express how saddened we are by this news.”
A “Rally for Bally” on 15 June to raise funds for Baltacha’s tennis academy and The Royal Marsden Cancer Charity was planned before her passing and is to be held in her honour at Queen’s Club, Birmingham and Eastbourne.
The most decorated player in women’s tennis, Martina Navratilova, is among the star names set to take part, alongside Andy Murray and Tim Henman.
Ukraine-born Baltacha, daughter of Ipswich footballer Sergei, won 11 ITF singles titles, most recently at the Aegon Nottingham Challenge last June.
She spent 132 weeks as British No1 and reached her highest world ranking of 49 in 2010.
She described competing at the London 2012 Olympics as “a dream come true”.
