objective a 4-month-old female with osteogenesis imperfecta (oi) type ii was admitted in picu of our center due to severe respiratory distress and fever with a diagnosis of severe pneumonia, and mechanical ventilation was initiated. due to severe hypotonia, ncv and emg were performed, and spinal muscular atrophy (sma) type i was diagnosed.

abstract objective autosomal recessive spinal muscular atrophy (sma) is, after cystic fibrosis, the second most common fatal monogenic disorder and the second most common hereditary neuromuscular disease after duchenne dystrophy. the disease is characterized by degeneration of anterior horn cells leading to progressive paralysis with muscular atrophy. depending on the clinical type (werdnig- ho...

spinal muscular atrophy (sma) is a genetic disorder which affect nervous system and is characterized with progressive distal motor neuron weakness. the survival motor neuron (smn) protein level reduces in patients with sma. two different genes code survival motor neuron protein in human genome. skeletal and intercostal muscles denervation lead to weakness, hypotony, hyporeflexia, respiratory fa...

spinal muscular atrophies (smas) represent a rare group of inherited disorders that cause progressive degeneration of the anterior horn cells of the spinal cord. the exact cause of the degeneration is unknown. loss of these cells results in a progressive lower motor neuron disease that has no sensory involvement and that is manifested as hypotonia, weakness, and progressive paralysis. kugelberg...

Spinal muscular atrophy (SMA) is a genetic disorder which affect nervous system and is characterized with progressive distal motor neuron weakness. The survival motor neuron (SMN) protein level reduces in patients with SMA. Two different genes code survival motor neuron protein in human genome. Skeletal and intercostal muscles denervation lead to weakness, hypotony, hyporeflexia, respiratory fa...

BACKGROUND Spinal muscular atrophy is an autosomal recessive disorder characterized by degeneration of anterior horn cells in the spinal cord leading to progressive muscular weakness and atrophy. The spinal muscular atrophy candidate interval genes including survival motor neuron, the responsible gene in spinal muscular atrophy phenotype expression, neuronal apoptosis inhibitory protein, and P4...

Autosomal dominant congenital spinal muscular atrophy is characterized by predominantly lower limb weakness and wasting, and congenital or early-onset contractures of the hip, knee and ankle. Mutations in TRPV4, encoding a cation channel, have recently been identified in one large dominant congenital spinal muscular atrophy kindred, but the genetic basis of dominant congenital spinal muscular a...

objective we describe three patients with very severe spinal muscular atrophy (sma) presented with reduced fetal movement in utero, profound hypotonia, severe weakness and respiratory insufficiency at birth. in all infants, electrodiagnostic studies were compatible with a neurogenic pattern. in genetic studies, all cases had homozygous deletions of exons 7 and 8 of survival motor neuron (smn) a...
