Model predicts scoliosis risk in patients receiving SMA treatment

An algorithm that takes into account clinical measures of motor symptom severity alongside data on factors like age and height may help predict the risk of scoliosis in people with spinal muscular atrophy (SMA) who have received disease-modifying treatment. “We trained a scoliosis classifier, demonstrating how data give rise…

Swallowing problems in SMA may be declining since advent of DMTs

Swallowing function may have improved in spinal muscular atrophy (SMA) patients since disease-modifying therapies (DMT) have become available, a review study suggests. The analysis showed problems with swallowing were prevalent in the years before the emergence of DMTs and that studies after the treatments became available indicated stabilizations…

Hand strength improves for adults with SMA types 2, 3 taking Evrysdi

Evrysdi (risdiplam) effectively improved motor function in adults with spinal muscular atrophy (SMA) type 2 or type 3, particularly skills like hand strength and function, a small study in France shows. Most patients also reported gains in bulbar functions, that is, speaking, chewing, and swallowing, and eased breath…

Unique BICD2 mutation causes severe SMA-LED: Case study

Researchers reported a unique mutation that supported an 8-year-old girl’s diagnosis of spinal muscle atrophy with lower extremity predominance (SMA-LED). The mutation, mapped to the BICD2 gene, resulted in a severe form of SMA-LED, type 2B, that emerged before birth and was primarily marked by joint contractures in infancy.

SMA’s effects on gene activity vary across tissues: Study

The activity of many genes may be dysregulated in spinal muscular atrophy (SMA), but the way the disease affects genes seems to vary across different types of tissues in the body, a study found. “Our comparative meta-analysis identified only few genes and pathways that were consistently dysregulated in SMA…
