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. It is comparable to the childhood-onset Kocher–Debré–Semelaigne syndrome. It is caused by low thyroid hormones (T3 and T4) with elevated TSH.
