Four proteins, BET1, HNRNPDL, NEFM and PHGDH, known to be involved in neurological diseases and dysregulated in WBC were further validated by muscle‐immunostainings unravelling HNRNPDL as a protein showing differences between VWA1‐patients, healthy controls and patients suffering from neurogenic muscular atrophy and BICD2‐related neuromyopathy. Here, VWA1 is linked to Skeletal muscle atrophy.
