Key Information
ATTRv V30M amyloidosis is often misdiagnosed as CIDP or diabetic neuropathy because all cause similar nerve pain. However, ATTRv does not respond to CIDP treatments like IVIG. Red flags for ATTRv include severe digestive issues, bilateral carpal tunnel syndrome, and a family history.
It is completely understandable to be confused by a changed diagnosis. Unfortunately, diagnostic delays of three to five years are extremely common for patients with hereditary transthyretin (ATTRv) amyloidosis, specifically the V30M variant [1]. Because the initial symptoms of ATTRv V30M look remarkably similar to other types of nerve damage, patients are frequently misdiagnosed with Chronic Inflammatory Demyelinating Polyneuropathy (CIDP) or diabetic neuropathy before the true cause is discovered
