Chronic childhood spinal muscular atrophies in Algeria
Journal of the Neurological Sciences, 1990This paper describes a genetic study of the chronic spinal muscular atrophies of late infancy and early childhood in Algeria. There were 50 index patients occurring in 44 kindreds and fourteen secondary cases. Genetic and nosological studies indicated that 52% of the patients constitute a genetically homogeneous subgroup with an age of onset between 3 ...

Current Concepts in Childhood Spinal Muscular Atrophy
Archives of Pediatrics & Adolescent Medicine, 1991There has been a surge of interest in neuromuscular disease in the past 2 years, sparked primarily by major genetic discoveries. While initial attention focused appropriately on Duchenne muscular dystrophy, the momentum has now swung to the spinal muscular atrophies, which, the authors note, are equally frequent and no less important in childhood ...

Spinal muscular atrophy in childhood
Diagnosis and classification of spinal muscular atrophy (SMA) in childhood are based on clinical, electrophysiological, and histological studies. The concept of maturational arrest of motoneurons and their targets (muscle cells in SMA type I) is documented by ultrastructural and immunohistochemical data.

Childhood spinal muscular atrophy
Spinal muscular atrophy (SMA) is caused by biallelic mutations in the SMN1 (survival motor neuron 1) gene on chromosome 5q13.2, which leads to a progressive degeneration of alpha motor neurons in the spinal cord and in motor nerve nuclei in the caudal brainstem.

Molecular prenatal diagnosis of autosomal recessive childhood spinal muscular atrophies (SMAs)
Gene, 2012Autosomal recessive childhood spinal muscular atrophy (SMAs) is the second most common neuromuscular disorder and a common cause of infant disability and mortality. SMA patients are classified into three clinical types based on age of onset, and severity of symptoms.

Spinal Muscular Atrophy in Childhood: Review of 50 Cases
SUMMARYThe clinical findings in 50 children with intermediate or mild spinal muscular atrophy are reviewed.An early age of onset and the presence of tongue fasciculation carry a poor prognosis for disability. Scoliosis appears early in nearly all children with the more severe forms of spinal muscular atrophy and early energetic treatment is indicated ...

Molecular Genetic Study of a Childhood Form of Spinal Muscular Atrophy
Molecular genetic studies were performed in 28 cases of childhood-onset spinal muscular atrophy (24 unrelated families). This consisted of type 1 (severe) (n = 5), type 2 (intermediate form) (n = 8), and type 3 (mild) (n = 15). Deletion of exons 7 and 8 of the SMNt gene was found in 100%, 100%, and 93%, respectively, in type 1, 2, and 3 spinal ...

Microcephaly and Mental Subnormality in Chronic Progressive Spinal Muscular Atrophy of Childhood
SUMMARYA wide variety of clinical manifestations are encountered in the various forms of progressive spinal muscular atrophy of childhood. The family reported here illustrates the relatively slowly progressive form of this disease. The presence of mental subnormality and microcephaly in this family is an unusual finding.Electromyographic and or muscle ...
