Data‐Driven Insights into Hyperkinetic Disorders in Neurodevelopmental Syndromes and Epileptic Encephalopathies

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Childhood‐onset hyperkinetic movement disorders occur in a range of genetic conditions. Recently, there has been an increase in recognition of hyperkinetic movement disorders, mainly dystonia, chorea and dyskinesia, with monogenic conditions associated with neurodevelopmental delay (NDD) and also with developmental and epileptic ...

SEQUENCE VARIANTS IN THE RYR1 GENE AND GENETIC DISEASES: MALIGNANT HYPERTHERMIA AND CONGENITAL MYOPATHIES

, 2009
This PhD thesis has been focused on the identification and functional characterization of sequence variants in the RYR1 gene, associated with Malignant hyperthermia (MH) and some congenital myopathies (CMs).

Autosomal recessive inheritance of RYR1 mutations in a congenital myopathy with cores

, 2002
Central core disease (CCD) is a congenital myopathy due to dominant mutations in the skeletal muscle ryanodine receptor gene (RYR1). The authors report three patients from two consanguineous families with symptoms of a congenital myopathy, cores on ...

Hyperhomocysteinemia and Vitamin B Deficiency as Potential Aggravating Factors in Huntington's Disease: A Prospective Monocentric Study

Movement Disorders, EarlyView.
Abstract Background Although not confirmed, some studies have suggested that elevated homocysteine levels are common in patients with Huntington's disease (HD). Its clinical relevance remains unclear. Objectives We aimed to assess vitamin B and homocysteine levels in HD patients and explore the relationships among hyperhomocysteinemia, vitamin B ...

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 ...

Congenital myopathies

Congenital myopathies (CMs) conform a large group of heterogeneous NMD with an ever-growing genotypic-phenotypic spectrum. CMs are caused by variants in at least 27 genes that code mostly for muscle proteins. The prevalence of CMs is 1.5 per 100,000, while the prevalence in the child population is higher.
