WebOct 1, 2024 · Transthyretin cardiac amyloidosis (ATTR-CA) is increasingly diagnosed owing to the emergence of noninvasive imaging and improved awareness. Clinical penetrance of pathogenic alleles is not complete and therefore there is a large cohort of asymptomatic transthyretin variant carriers. ... Transthyretin amyloid cardiomyopathy: … WebATTR amyloidosis is subdivided into a transthyretin wild-type form (ATTRwt) and a mutant (variant) form (ATTRv). ATTR might account for 13% of cases of HFpEF with left ventricular hypertrophy ≥12 mm. 8 The availability of specific, effective treatments for ATTR means that the diagnostic management of HFpEF should be improved.
WebIntroduction. Hereditary amyloidogenic transthyretin amyloidosis with polyneuropathy (ATTRv-PN) is an adult-onset, autosomal dominant disease produced by mutations in the TTR gene, which encodes the transthyretin (TTR) protein. 1 ATTRv-PN was thought to be endemic to Portugal, 2 Sweden, 3 and Japan, 4 however, an expanding number of … WebATTR can be inherited as an autosomal dominant trait caused by pathogenic variants in the transthyretin gene TTR (ATTRv) or by the deposition of ATTRwt (wild-type transthyretin protein), previously called senile cardiac amyloidosis. The ATTR amyloid protein can infiltrate other organs, most often the autonomic and peripheral nervous systems ...
WebIntroduction. Transthyretin (TTR) is the most common precursor protein of hereditary amyloidosis. Its phenotype is predominantly characterized by sensorimotor polyneuropathy and/or infiltrative cardiomyopathy (CM). 1,2 Moreover, TTR causes a nongenetic disease with deposition of wild-type (wt) TTR amyloid (ATTR) mainly in the heart of elderly …
