Hoffmann syndrome

Hoffmann syndrome

Hoffmann syndrome is a rare form of hypothyroid myopathy and is not to be confused with Werdnig-Hoffmann disease (a type of spinal muscular atrophy).

It was first documented in 1897 by Johann Hoffmann. It has adult-onset symptoms and is comparable to the childhood-onset Kocher–Debré–Semelaigne syndrome. It is caused by low thyroid hormones (T3 and T4) with elevated TSH.
