SPOT SMA is a prospective NIH-supported clinical study targeting pre-symptomatic or recently diagnosed infants and children with Spinal Muscular Atrophy (SMA) types 1, 2, or 3 and their healthy control siblings less than 36 months of age at the time of study enrollment. The main objective of the study is to prospectively collect longitudinal clinical outcomes and provide counseling and education to parents of newly diagnosed children. The study will assess the impact of current standard of care management paradigms and interventions on health outcomes in newly diagnosed SMA infants and children with type 1, 2 or 3 and age appropriate controls. There is no investigational drug and no specific intervention in this study. Rather, the investigators will document outcomes related to current therapies provided to participating subjects, and will educate participants about possible clinical trial opportunities.
Overview of data to be collected from enrolled infants followed longitudinally and entered into the NBSTRN Longitudinal Pediatric Data Resource
1. Past medical history relevant to pregnancy, delivery, complications in the immediate neonatal period, birth parameters, family history and any medical problems other than SMA (ie prematurity, etc)
2. Ongoing medical history indicating problems related to the following areas:
feeding, growth, respiratory status including use of cough assist and bilevel respiratory support, gastrointestinal issues, cardiac symptoms, neurologic symptoms or signs including muscle weakness, hospitalizations, ER visits, other adverse events
3. Assessment of dietary intake and use of nutritional supplements
4. Surgical history and ongoing documentation of assessments and need for g-tube, Nissen, tympanostomy, adenoidectomy/tonsillectomy or other airway surgeries, and orthopedic procedures
5. Caregiver obtained developmental history and documentation of newly acquired and/or loss of previously acquired gross motor skills at the time of each visit
6. Documentation of caregiver reported outcomes
7. Documentation of anthropometric measures, vital signs, general physical examination parameters
8. Neurological examination using standardized tools
9. Time to death, permanent invasive ventilation and/or need for > 16 hours/day of bilevel respiratory support
10. Specific assessment of motor function as measured using age appropriate motor outcome measures such as: the Children's Hospital of Philadelphia Infant Tests of Neuromuscular Disorders (CHOP-INTEND), Test of Infant Motor Performance Screening Inventory, WHO motor milestones or others, and Hammersmith Functional Motor Scale for SMA Expanded for children 18 months and older
11. Electrophysiologic studies such as maximum ulnar compound muscle action potential (CMAP) amplitude and area
12. Documentation of range of motion, development of limb contractures and/or presence of scoliosis, lordosis, hip dysplasia or other orthopedic outcomes
13. Additional optional exploratory biomarker assessments
14. DEXA measurements to assess body composition and bone density
15. The option to enroll in an autopsy study at the time of death to contribute samples to a research biorepository
Normal control subjects such as unaffected siblings will undergo these same measurements, as applicable. Unaffected parents' participation will be limited to collection and banking of blood and cell lines.

A group of disorders marked by progressive degeneration of motor neurons in the spinal cord resulting in weakness and muscular atrophy, usually without evidence of injury to the corticospinal tracts. Diseases in this category include Werdnig-Hoffmann disease and later onset SPINAL MUSCULAR ATROPHIES OF CHILDHOOD, most of which are hereditary. (Adams et al., Principles of Neurology, 6th ed, p1089)
An X-linked recessive form of spinal muscular atrophy. It is due to a mutation of the gene encoding the ANDROGEN RECEPTOR.
Disorders characterized by an abnormal reduction in muscle volume due to a decrease in the size or number of muscle fibers. Atrophy may result from diseases intrinsic to muscle tissue (e.g., MUSCULAR DYSTROPHY) or secondary to PERIPHERAL NERVOUS SYSTEM DISEASES that impair innervation to muscle tissue (e.g., MUSCULAR ATROPHY, SPINAL).
Diseases characterized by a selective degeneration of the motor neurons of the spinal cord, brainstem, or motor cortex. Clinical subtypes are distinguished by the major site of degeneration. In AMYOTROPHIC LATERAL SCLEROSIS there is involvement of upper, lower, and brainstem motor neurons. In progressive muscular atrophy and related syndromes (see MUSCULAR ATROPHY, SPINAL) the motor neurons in the spinal cord are primarily affected. With progressive bulbar palsy (BULBAR PALSY, PROGRESSIVE), the initial degeneration occurs in the brainstem. In primary lateral sclerosis, the cortical neurons are affected in isolation. (Adams et al., Principles of Neurology, 6th ed, p1089)
Longitudinal cavities in the spinal cord, most often in the cervical region, which may extend for multiple spinal levels. The cavities are lined by dense, gliogenous tissue and may be associated with SPINAL CORD NEOPLASMS; spinal cord traumatic injuries; and vascular malformations. Syringomyelia is marked clinically by pain and PARESTHESIA, muscular atrophy of the hands, and analgesia with thermoanesthesia of the hands and arms, but with the tactile sense preserved (sensory dissociation). Lower extremity spasticity and incontinence may also develop. (From Adams et al., Principles of Neurology, 6th ed, p1269)
