Research Interest:
The laboratory focuses on the neuromuscular disorder Spinal Muscular Atrophy (SMA). We developed the Delta 7 SMA mouse model that has been used extensively to develop therapeutics. Using this mouse model and many others we showed that the SMN protein is reduced in SMA and that the severity of the phenotype is dependent amount of functional SMN. We have shown rescue of SMA mice and pigs with scAAV9-SMN (Zolgensma) and this has led to approval of Zolgensma for treatment of SMA. Recently we demonstrated that co administration of an antisense oligo morpholino with a SMN inducing drug (Risdiplam) increase full-length SMN production from SMN2 and improved symptomatic treatment. We are currently using missense mutations identified in patients, along with suppressors, in mice and cell culture to study the oligomeric SMN protein and determine the critical function of SMN that gives rise to SMA. Finally, using bioinformatics we are studying the DNA differences in SMA patients whose SMN2 copy number does not correlate with the phenotypic SMA severity. We can potentially identify genes that modify the SMA phenotype.
