Severe scoliosis — an abnormal curvature of the spine — was significantly associated with older age and limited motor abilities in children with spinal muscular atrophy (SMA) type 2 who had not received disease-modifying therapies, a study showed. These findings establish characteristics of untreated scoliosis progression on SMA type…

Without disease-modifying treatment (DMT), spinal muscular atrophy (SMA) carries high mortality rates and steep healthcare costs, a study in Hong Kong reported. Not surprisingly, the greatest loss of life and highest costs were observed in children with SMA type 1, one of this disease’s most severe forms with…
A new system that contains a gene-modulating therapy attached to an antibody that enables crossing into the nervous system improved survival outcomes in a mouse model of severe spinal muscular atrophy (SMA), a new study reports. The study, “Antibody-oligonucleotide conjugate achieves central nervous system delivery in…
The one-time gene therapy Zolgensma (onasemnogene abeparvovec-xioi) was safe and effective in a baby girl with spinal muscular atrophy (SMA) type 1 who was previously on Evrysdi (risdiplam) for about three months, a case study reports. This likely represents the first report of safety and efficacy outcomes of…
Disease-modifying therapies (DMTs) used for spinal muscular atrophy (SMA) may contribute to the development of therapies for age-related progressive loss of muscle mass and strength, or sarcopenia, new research suggests. The survival muscle neuron (SMN) protein, whose deficiency causes SMA, was found at progressively lower levels with aging in…
Disease subtype, low body fat content, and shallow breathing and low blood oxygen levels during sleep are risk factors for recurrent lung infections and lung failure among children with spinal muscular atrophy (SMA), a study concluded. The risk of these lung complications was about five times higher in children…
PerkinElmer‘s EONIS system has been approved in the U.S. to be used by certified laboratories to simultaneously test newborns for spinal muscular atrophy (SMA) and severe combined immunodeficiency (SCID). The approval by the U.S. Food and Drug Administration (FDA) makes EONIS the first authorized test to be marketed…
Most people with spinal muscular atrophy (SMA) are unaware of their SMN2 copy number, and in a few cases, their type of SMA, according to a survey of Cure SMA members. Caregivers also may not know the number, the survey reported. Because an SMN2 copy number can determine…
A combination of in vitro fertilization and preimplantation genetic testing helped a couple in Indonesia — both carriers of mutations causing spinal muscular atrophy (SMA) — become parents of a healthy newborn, a case study reported. Their first daughter was diagnosed with SMA at 7 months, and she died of disease-related complications…
Researchers have developed and validated four new cell lines derived from four patients with spinal muscular atrophy (SMA) with lower extremity predominance (SMA-LED) that can be used as a tool in studies of this rare form of spinal muscular atrophy. With the characteristics of the patient it was…
