The Children’s Tumor Foundation is hosting its first L.A. Walk in 5K and 10K distances to benefit those who suffer from neurofibromatosis (NF) at 9 a.m. Saturday, October 7th, at Longs Drugs parking lot, 8900 Sepulveda West Way in Westchester.

Preregistration before Friday, September 29th, is $25 for singles and $50 for families (up to four members and $10 for each additional member).

On-site registration is $30 for singles and $55 for families (up to four members and $10 for each additional member).

Proceeds go directly to neurofibromatosis research. One in 3,500 individuals is said to have the disorder.

Event chairwoman Joyce Marks’s nine-year-old son Zach is also battling the condition.

Neurofibromatosis causes tumors to form on nerves anywhere in the body, including the brain and spinal cord.

The disorder can lead to loss of vision and hearing, disfigurement, loss of limbs, skeletal defects and various forms of cancer.

Half of all cases occur as the result of a “spontaneous genetic mutation” in families with no history of neurofibromatosis. There is no cure or effective treatment.

Registration and information, agordon@ctf.org or (310) 621-8339. Sponsorship forms can be downloaded at www.ctf.org/cali fornia
