MRPS33 and amyotrophic lateral sclerosis: In contrast, increased expression of MRPS33 (OR: 0.854; 95% CI: 0.807–0.902; p = 2.41 × 10−8) and LRPPRC (OR: 0.696; 95% CI: 0.623–0.778; p = 1.76 × 10−10) was linked to reduced ALS risk, highlighting protective mitochondrial ribosomal and RNA processing roles.
