Germline variants in MYH3 are associated with distal arthrogryposis syndromes [distal arthrogryposis type 1, Freeman-Sheldon syndrome (DA2A), and Sheldon-Hall syndrome (DA2B)], multiple pterygium syndrome (MPS), and spondylocarpotarsal synostosis syndrome (SCT) [74–77]. This evidence concerns the gene MYH3 and mucopolysaccharidosis.
