Ja. Palha et al., C-SUBSTITUTION FOR T-SUBSTITUTION AT CODON-108 - THE FIRST IDENTIFIEDSILENT MUTATION IN THE TRANSTHYRETIN GENE, AMYLOID-INTERNATIONAL JOURNAL OF EXPERIMENTAL AND CLINICAL INVESTIGATION, 4(1), 1997, pp. 52-53
Transthyretin (TTR) is a 55 kDA tetrameric protein synthesized by the
liver and the choroid plexus that binds thyroxine and retinol-binding
protein. More than fifty mutations have been identified in the TTR gen
e, the majority of them associated with hereditary amyloidosis.(1) Thi
s study reveals the first silent mutation on the TTR gene:Ala108.
