We show that the intranuclear organization of chromosomes is not altered in cells that lack the integral nuclear membrane protein emerin, from an individual with X-linked Emery--Dreifuss muscular dystrophy.
We report a striking abundance of rimmed vacuoles in two brothers with X-linked Emery-Dreifuss muscular dystrophy (X-EDMD) confirmed by the absence of emerin at the muscular nuclear envelope and by genetic analysis showing a new 2-bp deletion in exon 6 of the STA gene at the Xq28 region.

We present here the relationship between emerin protein expression, nuclear localization and clinical phenotype for two distal mutations identified in unrelated EDMD patients.
We infer that the EDMD1 phenotype may be strengthened by the toxicity of truncated emerin expressed in patients with certain nonsense mutations in <i>EMD</i>.
To describe the clinical variability of X-linked Emery-Dreifuss muscular dystrophy (X-EDMD) with cardiac involvement in a four-generation family with a novel mutation in the STA gene.
To describe the clinical variability of X-linked Emery-Dreifuss muscular dystrophy (X-EDMD) with cardiac involvement in a four-generation family with a novel mutation in the STA gene.
These results confirmed the diagnosis of X-linked Emery-Dreifuss muscular dystrophy (EDMD), and reinforce the necessity of molecular genetic diagnosis of the membrane protein emerin in younger patients with possible EDMD before appearance of the typical symptoms, to avoid sudden cardiac death.
There is a suggestion of linkage between EDMD and the loci DXS52 and DXS15, defined by probes St14 and DX13 respectively, located at Xq28.Z for DXS15 = 1.14 at theta = 0.15.
The XCI pattern was determined on the lymphocytes of 30 symptomatic and asymptomatic EDMD1 female carriers-25 familial and 5 sporadic cases-seeking genetic advice using the androgen receptor (AR) methylation-based assay.
The product of the X-linked Emery-Dreifuss muscular dystrophy gene is a single-membrane-spanning protein called emerin, which is localized to the inner nuclear membrane of all tissues studied.
SSCP detection of novel mutations in patients with Emery-Dreifuss muscular dystrophy: definition of a small C-terminal region required for emerin function.
Our patient broadens the pathological spectrum of VCP-myopathy and emphasizes the importance of VCP analysis in patients with scapuloperoneal muscular dystrophy despite the absence of Paget disease, dementia, rimmed vacuoles, or intracellular amyloid deposition.
