Expression of several genes linked to motor neuronopathy and familiar amyotrophic lateral sclerosis (EPHA4, IGHMBP2, VAPB, BICD2, and DYNC1H1) or distal arthrogryposis (MYH8, ZC4H2, MUSK, RAPSN) were significantly upregulated or downregulated. The gene discussed is BICD2; the disease is distal arthrogryposis.
