BACKGROUND: Mutations of transthyretin (TTR) cause the most common type of
autosomal-dominant hereditary systemic amyloidosis, which occurs worldwide. To
date, more and more mutations in the TTR gene have been reported. Some variations
in the clinical presentation are often observed in patients with the same
mutation or the patients in the same family. The purpose of this study was to
find out the clinicopathologic and genetic features of Chinese patients with
hereditary TTR amyloidosis. METHODS: Clinical and necessary examination materials
were collected from nine patients of eight families with hereditary TTR
amyloidosis at Peking University First Hospital from January 2007 to November
2014. Sural nerve biopsies were taken for eight patients and skin biopsies were
taken in the calf/upper arm for two patients, for light and electron microscopy
examination. The TTR genes from the nine patients were analyzed. RESULTS: The
onset age varied from 23 to 68 years. The main manifestations were paresthesia,
proximal and/or distal weakness, autonomic dysfunction, cardiomyopathy, vitreous
opacity, hearing loss, and glossohypertrophia. Nerve biopsy demonstrated severe
loss of myelinated fibers in seven cases and amyloid deposits in three. One
patient had skin amyloid deposits which were revealed from electron microscopic
examination. Genetic analysis showed six kinds of mutations of TTR gene,
including Val30Met, Phe33Leu, Ala36Pro, Val30Ala, Phe33Val, and Glu42Gly in exon
2. CONCLUSIONS: Since the pathological examinations of sural nerve were negative
for amyloid deposition in most patients, the screening for TTR mutations should
be performed in all the adult patients, who are clinically suspected with
hereditary TTR amyloidosis.
