Summaries for Spinal Muscular Atrophy, X-Linked 2

OMIM : 57 X-linked infantile spinal muscular atrophy (XL-SMA) is characterized by neonatal onset of severe hypotonia, areflexia, and multiple congenital contractures, known as arthrogryposis, associated with loss of anterior horn cells and infantile death (summary by Ramser et al., 2008). Historically, Hall et al. (1982) distinguished at least 3 clinical varieties of X-linked arthrogryposis. (1) One family had a severe lethal form with severe contractures, scoliosis, chest deformities, hypotonia, micrognathia, and death from respiratory insufficiency by age 3 months. Apparently progressive loss of anterior horn cells was the cause. (2) Two families had moderately severe AMC associated with ptosis, microphallus, cryptorchidism, inguinal hernias, and normal intelligence. Nonprogressive intrauterine myopathy appeared to be the 'cause'. (3) In 2 families and a sporadic case, the disorder took the form of a resolving AMC, with mild to moderate contractures improving dramatically with time, normal intelligence, and no other anomalies; tight connective tissues on misplaced tendons was postulated.

MalaCards based summary : Spinal Muscular Atrophy, X-Linked 2, also known as arthrogryposis multiplex congenita, distal, x-linked, is related to congenital contractures and spinal muscular atrophy, and has symptoms including facial paresis An important gene associated with Spinal Muscular Atrophy, X-Linked 2 is UBA1 (Ubiquitin Like Modifier Activating Enzyme 1). The drugs Racepinephrine and Epinephrine have been mentioned in the context of this disorder. Affiliated tissues include bone, testes and spinal cord, and related phenotypes are gait disturbance and joint stiffness

Genetics Home Reference : 25 X-linked infantile spinal muscular atrophy is a condition that affects only boys and is characterized by severe muscle weakness and absent reflexes (areflexia). Affected children often have multiple joint deformities (contractures) from birth that cause joint stiffness (arthrogryposis) and impair movement. In severe cases, affected infants are born with broken bones. The muscle weakness worsens over time; affected children reach some early motor developmental milestones, such as sitting unassisted, but these skills are often lost (developmental regression). Additional features of X-linked infantile spinal muscular atrophy include an unusually small chin (micrognathia), abnormal curvature of the spine (scoliosis or kyphosis), and undescended testes (cryptorchidism). Weakness of the chest muscles used for breathing often leads to life-threatening breathing problems. Children with X-linked infantile spinal muscular atrophy usually do not survive past early childhood due to respiratory failure, although, in rare cases, affected individuals can survive into adolescence.

NIH Rare Diseases : 53 The following summary is from Orphanet, a European reference portal for information on rare diseases and orphan drugs.Orpha Number: 1145DefinitionX-linked distal arthrogryposis multiplex congenital (SMAX2) is a 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.Visit the Orphanet disease page for more resources.

UniProtKB/Swiss-Prot : 74 Spinal muscular atrophy X-linked 2: A lethal infantile form of spinal muscular atrophy, a neuromuscular disorder characterized by degeneration of the anterior horn cells of the spinal cord, leading to symmetrical muscle weakness and atrophy. Clinical features include hypotonia, areflexia, and multiple congenital contractures.
