Additionally, the contribution of rare genetic variations to idiopathic inflammatory myopathies (IIMs) has been investigated, revealing significant associations that align with previous gene expression profiling findings (ref: Bianchi doi.org/10.1002/art.41929/). This highlights the heterogeneity of IIMs and the potential for targeted genetic research to uncover novel therapeutic avenues. In a clinical context, a phase 2 study evaluated the safety and efficacy of N-acetylmannosamine (ManNAc) in patients with GNE myopathy, demonstrating promising biochemical efficacy and safety profiles (ref: Carrillo doi.org/10.1038/s41436-021-01259-x/). These findings not only advance our understanding of the molecular underpinnings of myopathies but also pave the way for innovative therapeutic strategies aimed at addressing these complex disorders.
