SMA 4 (Adult onset) Adulthood This denotes the adult-onset form, sometimes also classified as a late-onset SMA type 3. It occurs in approx. 5% of patients and usually manifests in the third or fourth decade of life. The symptoms consist of gradual weakening of leg muscles, which frequently makes it necessary for the patient to use walking aids.
Distal spinal muscular atrophy type 1 (DSMA1) Spinal muscular atrophy with respiratory distress type 1 (SMARD1) Distal hereditary motor neuronopathy type 6 (DHMN6) 604320: IGHMBP2: 11q13.3: Autosomal recessive: Affects mainly infant boys, similar to SMA type 1 but with diaphragmatic paralysis Distal spinal muscular atrophy type 2 (DSMA2)
Jokela type spinal muscular atrophy (SMAJ), also known as late-onset spinal motor neuronopathy (LOSMoN), is an ultra-rare neuromuscular disorder characterized by muscle twitches and cramps. [1] The symptoms appear in adulthood and gradually progress.
Spinal and bulbar muscular atrophy (SBMA), popularly known as Kennedy's disease, is a rare, adult-onset, X-linked recessive lower motor neuron disease caused by trinucleotide CAG repeat expansions in exon 1 of the androgen receptor (AR) gene, which results in both loss of AR function and toxic gain of function.
Distal spinal muscular atrophy type 1 (DSMA1), also known as spinal muscular atrophy with respiratory distress type 1 (SMARD1), is a rare neuromuscular disorder involving death of motor neurons in the spinal cord which leads to a generalised progressive atrophy of body muscles.
Distal hereditary motor neuronopathies (distal HMN, dHMN), sometimes also called distal hereditary motor neuropathies, are a genetically and clinically heterogeneous group of motor neuron diseases that result from genetic mutations in various genes and are characterized by degeneration and loss of motor neuron cells in the anterior horn of the spinal cord and subsequent muscle atrophy.
These changes are “leading to a rise in new-onset adult allergies,” says Ogden. 2. Hormonal changes and pregnancy. Allergies while pregnant? Maybe. Studies show 1/3 of pregnant women develop ...

Specialty: Neurology: Symptoms: Progressive muscle atrophy in legs: Usual onset: Infancy: Causes ...
