Presentation
We present the first report of a Korean family with HGA diagnosed by WES. WES facilitated a clinical diagnosis of HGA in patients with undiagnosed neuropathies. [ncbi.nlm.nih.gov]

Laboratory Technician
Acknowledgments We are grateful to Ari Frilander, BSc, Tuija Järvinen and Ilse Pyy, laboratory technicians, for skilled technical assistance. We thank Dr. Blas Frangione for the amyloid A and variant cystatin C antibodies, and Dr. [academic.oup.com]

Dysphagia
Muscular weakness, dysphagia, and macroglossia are observed in some older AGel amyloidosis patients ( 2 ) and may reflect amyloid myopathy ( 33, 34 ). [academic.oup.com]

Tongue Atrophy
A 58-yr-old man presented with involuntary facial twitching, progressive bilateral facial weakness, and tongue atrophy. His mother, maternal uncle, two sisters, and son suffered from the same symptoms. [ncbi.nlm.nih.gov]

Areflexia

Aged patients may show severe bulbar signs, profound loss of vibratory sensitivity with areflexia, unsteady gait, and manual clumsiness ( 4 ). Autonomic dysfunction is mild ( 6 ). [academic.oup.com]

Kidney Failure
Kidney failure often dominates the clinical picture and a kidney transplant may effectively restore normal health for a long time. [ucl.ac.uk]
In some cases, the amyloid deposits will cause the kidneys to lose the ability to purify the blood, which can lead to kidney failure; also known as “renal” failure. These patients may need dialysis to replace the function of the kidneys. [amyloidosis.org]
Workup
Following this workup the patient should undergo a DNA analysis and tissue biopsy (Table 1 ), although the uneven distribution of amyloid fibrils may yield false-negative results. [ojrd.biomedcentral.com]
Treatment
In HGA, specific therapy is not yet available but correct diagnosis enables adequate symptomatic treatment which decisively improves the quality of life in these patients. [ncbi.nlm.nih.gov]
Treatment Treatment Options: Penetrating keratoplasty can be beneficial but is rarely needed for visual rehabilitation. The amyloid deposits may recur in the donor tissue. [disorders.eyes.arizona.edu]
She had been referred to the Ophthalmology Division at Hospital de Clinicas in Buenos Aires for diagnosis and treatment. [karger.com]
Prognosis
In some cases that present with extremely low visual acuity due to corneal scarring, a corneal transplant could be performed, but prognosis is very poor [ 11 ]. [karger.com]

The prognosis depends very much on the degree of response to treatment, which varies between patients. [ucl.ac.uk]
The symptoms, as well as the prognosis, depend on the tissue and organ(s) affected by the amyloid deposits. [amyloidosis.org]
Etiology
To identify the etiology of the undiagnosed neuropathy, we performed whole-exome sequencing (WES) following written informed consent. Germline DNA was obtained from the four individuals ( Fig. 1A ). [synapse.koreamed.org]
This has also proved to be valid for assessing other etiologic forms of amyloidotic cardiomyopathy [ 70 ]. Pericardial effusion is another frequent finding in cardiac amyloidosis. [ojrd.biomedcentral.com]

Pathophysiology As with other amyloid diseases, LCD2 is based on misfolded proteins forming β-sheets instead of α-helices creating fibrillar amyloid structures that accumulate in affected organs to cause pathology. [webeye.ophth.uiowa.edu]

The clinical spectrum of cardiovascular involvement is wide, ranging from asymptomatic AV and bundle branch block to severe, rapidly progressive heart failure due to restrictive pathophysiology. [ojrd.biomedcentral.com]
