To further improve the clinical applicability, we identified 12 PCD-related genes that affected the prognosis of MM using stepwise regression analysis, including HMGB3, IL24, CD38, GZMB, RHOC, CEACAM1, FABP5, HPDL, SHROOM3, WNT9A, FOXD1, and TJP1. The gene discussed is HPDL; the disease is Miyoshi myopathy.
