Clinical characteristics in patients with hereditary amyloidosis with Glu54Gln transthyretin identified in the Romanian population.

This is the largest Glu54Gln-mutated ATTRh cohort diagnosed to date, and to our knowledge the first describing this variant worldwide. Clinical features of this variant are early onset, neurological and cardiac involvement, aggressive disease progression and short survival. Early diagnosis and therapeutic intervention have potential to improve prognosis in ATTRh.
