Connect with an ALSP Clinical Expert

Once your neurologist suspects or confirms your diagnosis as ALSP caused by a mutation on the CSF1R gene, it’s important to get connected to the right experts. Due to the complexity of this rare disease, it’s likely your care team has never encountered another patient with this condition. It’s imperative that you or your family member receive the most innovative options for treatment and management of the disease.
The following clinical experts have been identified as leaders in the care and clinical management of ALSP. These clinicians have expressed an interest in caring for or treating ALSP patients. As a rare disease organization, we are grateful for each of the listed experts whom are well known around the world for their program and can meet the extensive medical needs of patients with ALSP.
We hope this list will be helpful to you – or your loved one – as you seek out qualified, quality, and experienced care.

Please Note: The publication of this list by the Sisters' Hope Foundation is not intended as, nor does the publication constitute, the recommendation, approval or endorsement, by the Foundation of any of the clinicians whose names appear on the list.
