Cytoplasmic dynein 1 heavy chain 1 is a protein that in humans is encoded by the DYNC1H1 gene.[1][2][3]


DYNC1H1 has been shown to interact with PAFAH1B1[4] and CDC5L.[5]

Clinical relevance

Mutations in this gene have been shown to cause dominant axonal Charcot-Marie-Tooth disease[6] as well as spinal muscular atrophy with lower extremity predominance (SMA-LED).[7]
