PHILADELPHIA -- Philadelphia 76ers center Todd MacCulloch has been diagnosed with Charcot-Marie-Tooth disease, a neurological disorder that causes damage to the peripheral nerves.

It's uncertain when he'll return to action. MacCulloch is scheduled to see a specialist Monday. The disease is named after three doctors who first diagnosed it in 1886.

"A lot of people have CMT and are able to live normal lives, so that's a good thing,'' MacCulloch said. "It's not life threatening. It usually affects your peripheries and things like that. A lot of people live full, happy lives.''

MacCulloch, acquired last summer with Keith Van Horn in the trade that sent Dikembe Mutombo to New Jersey, has been bothered by foot problems all season. He has missed 15 games and has averaged 7.1 points and 4.7 rebounds in 19.3 minutes per game.

"There is no definite ruling on his career or on this season,'' Sixers general manager Billy King said.
