Review of Congenital Myasthenic Syndrome Caused by Pathogenic Variants in GFPT1

Muscle &Nerve, EarlyView.
ABSTRACT Glutamine:fructose‐6‐phosphate transaminase 1 (GFPT1) catalyzes the first and rate‐limiting step of the hexosamine biosynthetic pathway (HBP) to generate UDP‐GlcNAc. GFPT1 exon 9 is specifically spliced in in striated muscles, which makes a long isoform of GFPT1 (GFPT1‐L).

AGRN‐, LRP4‐, MUSK‐Related CMS: Clinical, Neurophysiological, Morphological, Genetic and Pathological Mechanisms

Muscle &Nerve, EarlyView.
ABSTRACT Congenital myasthenic syndromes (CMS) are inherited disorders caused by mutations in genes encoding proteins essential for neuromuscular junction (NMJ) function. Pathogenic variants have been identified in more than 35 genes, underscoring the complexity of synaptic biology and the wide range of mechanisms that can compromise neuromuscular ...

Presynaptic Congenital Myasthenic Syndromes

Muscle &Nerve, EarlyView.
ABSTRACT Presynaptic congenital myasthenic syndromes (CMS) encompass a large number of rare neurologic disorders caused by impaired release of acetylcholine (ACh) from motor nerve terminals. There are two main groups of presynaptic CMS: one in which the amount of ACh in synaptic vesicles (SV) is diminished and another in which the mechanism of synaptic

The Differing Phenotypes of the Three Most Common Postsynaptic Congenital Myasthenic Syndromes Governed by Their Underlying Molecular Pathogenic Mechanisms

Muscle &Nerve, EarlyView.
ABSTRACT The congenital myasthenic syndromes are rare disorders of impaired signal transmission at the neuromuscular junction. Despite next generation sequencing facilitating the identification of variants in myasthenic‐associated genes, these variants are frequently of unknown significance and the clinical diagnosis can be delayed.

Clinical Characteristics and Treatment Management of Seronegative Myasthenia Gravis: A Systematic Review of the Literature

Muscle &Nerve, EarlyView.
ABSTRACT Seronegative myasthenia gravis (SNMG) is characterized by the absence of detectable autoantibodies against known MG targets, despite clinical and electrophysiological evidence of a postsynaptic neuromuscular junction disorder. The aim of this systematic review was to better define clinical features, diagnostic clues and treatment outcome of ...
