Contractures, pterygia, and spondylocarpotarsal fusion syndrome-1B (CPSFS1B) is characterized by contractures of proximal and distal joints, pterygia involving the neck, elbows, fingers, and/or knees, and variable vertebral, carpal, and tarsal fusions. Inter- and intrafamilial variability has been observed (Cameron-Christie et al., 2018).
An autosomal dominant form of contractures, pterygia, and spondylocarpotarsal fusion syndrome (CPSFS1A; 178110) is caused by heterozygous mutation in the MYH3 gene.
