Per Abdelnaseer et al., higher serum MMP-9 within 24 h after AIS was associated with worse functional outcome after 1 month post-stroke, while higher MMP-9 levels 30 days after AIS were associated with both high NIHSS at baseline and a good functional outcome at 1 month (Abdelnaseer et al., 2017). The gene discussed is MMP9; the disease is androgen insensitivity syndrome.
