OBJECTIVE
To identify the gene defect that causes blindness and the predisposition to embryonic death in the retinopathy globe enlarged (rge) chicken.
METHODS
Linkage analysis, with previously uncharacterized microsatellite markers from chicken chromosome 1, was performed on 138 progeny of an rge/+
We describe a 34-year-old patient who was admitted with episodic diplopia, ptosis, and swallowing difficulties of 6 months duration. He also had some muscle cramps aggravated by exercise since the age of 20. Bilateral ptosis of the eyelids, normal gaze, rare fasciculations of the tongue, easy
OBJECTIVE
Spinal and bulbar muscular atrophy (SBMA), also known as Kennedy disease, is a rare neurodegenerative disorder presenting with insidious onset of weakness in bulbar and limb muscles. Information regarding long-term clinical and functional progression has been limited, especially for the
To gain insight into the pathophysiology of vitreoretinal degeneration, the clinical course of three family members with Versican Vitreoretinopathy (VVR) is described, and a canonical splice site mutation in the gene encoding for versican (VCAN) protein was biochemically Photoreceptor cell degeneration leads to visual impairment and blindness in several types of retinal disease. However, the discovery of safe and effective therapeutic strategies conferring photoreceptor cell protection remains challenging. Targeting distinct cellular pathways with low doses of
We report a patient with sporadic amyotrophic lateral sclerosis (ALS) with a novel fusion in malignant liposarcoma (FUS) gene mutation whose neurological signs were conspicuous left-sided rigidity and apraxia. A novel heterozygous guanine (G)-to-thymine (T) transition at position 1392, c.1392G>T,
There is a failure of growth in hypoxanthine guanine phosphoribosyltransferase deficiency; slow weight gain is marked after the second year of age but is apparent in the birth weights of all eight of our patients for whom we have data. However, head growth and bone development are less affected than
A universal base that is capable of substituting for any of the four natural bases in DNA would be of great utility in both mutagenesis and recombinant DNA experiments. This paper describes the properties of oligonucleotides incorporating two degenerate bases, the pyrimidine base
X-linked muscular atrophy is a form of adult-onset, usually slowly progressive spinal and bulbar motor neuron degenerative disease that is uniquely associated with male hypogonadism. The mutation responsible for this syndrome is expansion of the trinucleotide repeat-cytosine (C), adenine (A),
OBJECTIVE
To investigate genetics and clinical characteristics of dentatorubral-pallidoluysian atrophy (DRPLA) in Chinese kindreds.
METHODS
Fragment analysis with laser-induced fluorescence in capillary electrophoresis was performed for the cytosine-adenine-guanine (CAG) repeats of DRPLA gene in 708
Dentatorubropallidoluysian atrophy (DRPLA) is a neurodegenerative disease caused by an expansion of a cytosine-adenine-guanine (CAG) repeat encoding a polyglutamine tract in the atrophin-1 protein. Unlike other CAG repeat diseases, sleep related problems have not been reported in patients with
Specific degenerate codons in the amino-terminal region of a synthetic human parathyroid hormone (PTH) gene exerted dramatic effects on both products and yield of expression of this 84-amino acid polypeptide in Escherichia coli. With adenine-rich degenerate codons constituting the PTH-(1-5) region,
Neuronal damage induced by injury, stroke, or neurodegenerative disease elicits swift immune responses from glial cells, including altered gene expression, directed migration to injury sites, and glial clearance of damaged neurons through phagocytic engulfment. Collectively, these responses hinder
Mutations in proteins of the Drosophila phototransduction cascade, a prototypic guanine nucleotide-binding protein-coupled receptor signaling system, lead to retinal degeneration and have been used as models to understand human degenerative disorders. Here, modulating the sphingolipid biosynthetic
