granulomatous myositis-specific gene signature

This is a granulomatous myositis-associated transcriptomic signature derived from muscle biopsy RNA sequencing. The abstract states that it distinguishes GM and correlates with disease activity markers.

The abstract indicates that bulk RNA sequencing of muscle biopsies was used, and support vector machine models were applied to the resulting signature.

It addresses the need to define a specific transcriptomic profile for granulomatous myositis and to identify GM accurately from biopsy-derived expression data.

The abstract does not show that the signature is a therapeutic intervention or that it generalizes beyond the reported biopsy cohorts.

The abstract contrasts GM biopsies with other myopathies and healthy comparators, but it does not name an alternative diagnostic signature.
