Genetically undefined CMT
Families/people with genetically undefined CMT with common causes ruled out.
- Charcot Marie Tooth disease type 1A (CMT1A) gene modifiers [ Time Frame: once ]While the same genetic change - an extra copy of PMP22 - causes CMT1A by definition, it is unclear why some people have more severe symptoms and some have less severe. We are looking for genetic modifiers - changes in the DNA that may be causing the differences in symptoms.
- New genetic causes of CMT [ Time Frame: Once ]At least 33% of people with CMT have an unknown or genetically un-found form of the condition. We are looking for additional genes that cause CMT when mutated.
Biospecimen Retention: Samples With DNA
