Infantile-onset X-linked spinal muscular atrophy
MONDO:0010532A rare form of spinal muscular atrophy characterized by the neonatal onset of severe hypotonia, areflexia, profound weakness, multiple congenital contractures, facial dysmorphic features (myopathic face with open, tent-shaped mouth), cryptorchidism, and mild skeletal abnormalities (i.e. kyphosis, scoliosis), that is often preceded by polyhydramnios and reduced fetal movements in utero and followed by bone fractures shortly after birth. SMAX2 patients often have a limited life span, often succumbing to the disease within 2 years, as muscle weakness is progressive and chest muscle involvement eventually leads to ventilatory insufficiency and respiratory failure.
Also known as: SMAX2, X-linked distal arthrogryposis multiplex congenita, X-linked spinal muscular atrophy type 2, spinal muscular atrophy with arthrogryposis, spinal muscular atrophy, X-linked 2, infantile, X-linked recessive, spinal muscular atrophy, X-linked type 2, AMC, distal, X-linked, arthrogryposis multiplex congenita, distal, X-linked

Mind-Controlled tablets: brain implant trial aims to give voice to the paralyzed
Disease control Recruiting nowThis early-stage trial tests a brain-computer interface called BrainGate for people with paralysis from conditions like ALS or spinal cord injury. A small sensor is placed in the brain to interpret movement-related signals, allowing users to control a tablet computer just by thin…

Smart trial takes on MND: could existing drugs slow the disease?
Disease control Recruiting nowThis study tests several already-approved drugs to see if they can slow down motor neuron disease (MND) and help people live longer. About 1150 adults with MND will be randomly assigned to receive one of the study drugs or a placebo. The trial uses a flexible design, allowing ine…

Ultra-Strong MRI scans could spot ALS earlier
Diagnosis Recruiting nowMotor neuron disease (MND), including ALS, is hard to diagnose and often takes years to confirm. This pilot study uses a powerful 7 tesla MRI scanner to look for detailed brain features, called imaging biomarkers, that are specific to MND and its subtypes. Researchers will scan 3…
