Guidelines for genetic counselling in ATTR amyloidosis
نویسنده
چکیده
Definition Genetic counselling is “a process of communication that deals with the occurrence, or risk of occurrence, of a (possibly) genetic disorder in the family” (ASHG, 1975; EuroGentest guidelines). It involves an attempt, by appropriately trained persons, to help patients and their families to (1) understand the medical facts of the disease; (2) appreciate the contribution of heredity and risks of recurrence in relatives; (3) understand the consultands’ options to deal with those risks, including all their reproductive options; (4) use this genetic information in a personally meaningful way that promotes health, minimizes psychological distress and increases personal control; (5) choose the course of action that seems appropriate to them and act in accordance with that decision; and (6) make the best possible adjustment to the disease or the genetic risks (modified by EuroGentest Unit 3 from Frazer, AJHG 1974; Biesecker & Peters, AJMG 2001; Harper, 2012).

Frequencies and geographic distributions of genetic mutations in transthyretin- and non-transthyretin-related familial amyloidosis.
Inherited forms of amyloidosis are rare; of these, transthyretin-related (ATTR) is the most common, but non-ATTR has been described as well. We studied a large case series of ATTR and a small series of non-ATTR to better determine the mutation frequencies and geographic distributions of these inherited forms of amyloidosis in the United States. We performed a retrospective cross-sectional study...
متن کاملGene expression profile in hereditary transthyretin amyloidosis: differences in targeted and source organs
INTRODUCTION Hereditary transthyretin amyloidosis (ATTR) is a genetic disease caused by a point mutation in the TTR gene that causes the liver to produce an unstable TTR protein. The most effective treatment has been liver transplantation in order to replace the variant TTR producing liver with one that produces only wild-type TTR. ATTR amyloidosis patients' livers are reused for liver sick pat...
متن کامل(99m)Tc-pyrophosphate scintigraphy for differentiating light-chain cardiac amyloidosis from the transthyretin-related familial and senile cardiac amyloidoses.
BACKGROUND Differentiating immunoglobulin light-chain (AL) from transthyretin-related cardiac amyloidoses (ATTR) is imperative given implications for prognosis, therapy, and genetic counseling. We validated the discriminatory ability of (99m)Tc-pyrophosphate ((99m)Tc-PYP) scintigraphy in AL versus ATTR. METHODS AND RESULTS Forty-five subjects (12 AL, 16 ATTR wild type, and 17 ATTR mutants) un...

Background—Differentiating immunoglobulin light-chain (AL) from transthyretin-related cardiac amyloidoses (ATTR) is imperative given implications for prognosis, therapy, and genetic counseling. We validated the discriminatory ability of Tc-pyrophosphate scintigraphy (TcPYP) in AL vs. TTR-related cardiac amyloidoses. Methods and Results—45 subjects (12 AL, 16 ATTR wild-type, and 17 ATTR mutants)...
متن کاملCharacterization of conformation-specific, human-derived monoclonal antibodies against TTR aggregates with potential for diagnostic and therapeutic use
Misfolding and aggregation of transthyretin (TTR) is the basic pathophysiological mechanism of hereditary and wild type TTR amyloid (ATTR) amyloidosis. Polyneuropathy and/or cardiomyopathy with heart failure dominates the clinical presentation of the disease. Conformational changes of the TTR protein structure produce toxic intermediates that introduce cell death and ultimately loss of organ fu...
