SPINAL muscular atrophy (SMA) describes a group of heritable degenerative diseases that selectively affect the α-motor neuron. Childhood-onset SMAs rank second in frequency to cystic fibrosis among autosomal recessive disorders, and are the leading cause of heritable infant mortality. Predictions that genetic heterogeneity underlies the differences between types of SMA, together with the aggressive nature of the most-severe infantile form, make linkage analysis of SMA potentially complex. We…

Genetic homogeneity between acute and chronic forms of spinal muscular atrophy
THE childhood-onset spinal muscular atrophies (SMAs) describe a heterogeneous group of disorders that selectively affect the alpha motoneuron. We have shown that chronic childhood-onset SMA (SMA II…
Mapping of acute (type I) spinal muscular atrophy to chromosome 5q12-q14
Deletions in the survival motor neuron gene in Turkish spinal muscular atrophy patients
TLDR
Three candidate genes have been identified in the SMA region and single base substitutions in exons 7 and 8 allow distinction between SMN, the telomeric copy, and cBCD541, the centromeric copy of the survival motor neuron gene.
De novo and inherited deletions of the 5q13 region in spinal muscular atrophies.
TLDR
Results indicate that deletion events are statistically associated with the severe form of spinal muscular atrophy.

Clinical and molecular analysis of spinal muscular atrophy in Brazilian patients
TLDR
Two candidate genes, the survival motor neuron (SMN) gene and the neuronal apoptosis inhibitory protein (NAIP) gene, have been identified; SMN is deleted in most SMA patients; correlation between deletions of one or both genes and phenotype severity was found.

Childhood-onset proximal spinal muscular atrophy (SMA) is characterized by degeneration of the anterior horn cells of the spinal cord leading to symmetrical limb and trunk paralysis. SMA is the…
Large scale deletions of the 5q13 region are specific to Werdnig-Hoffmann disease.
TLDR
The presence of large scale deletions involving these loci is specific to Werdnig-Hoffman disease (type I) and allows one to predict the severity of the disease in this series.
Molecular analysis of patients with recessive 5q-spinal muscular atrophy : increased diagnostic and prognostic sensitivity /
TLDR
The results of studies designed to increase understanding of the prognostic value of SMN2 gene copy number in the modification of the SMA phenotype are presented, as well as to increase the diagnostic sensitivity of molecular analysis o f spinal muscular atrophy patients.

Patients with this characteristic clinical syndrome comprise approximately one-fifth of children with chronic spinal muscular atrophy, and management should be based on vigorous antibiotic therapy, orthopaedic and neurological surveillance, and a carefully planned educational programme aimed at realistic employment in late adolescence.
