Ullrich congenital muscular dystrophy 2

An Ullrich congenital muscular dystrophy characterized by joint hypermobility, proximal contractures, and muscle weakness precluding ambulation that has_material_basis_in homozygous mutation in the COL12A1 gene on chromosome 6q.

Ullrich congenital muscular dystrophy 1A

An Ullrich congenital muscular dystrophy characterized by generalized muscle weakness and striking hypermobility of distal joints in conjunction with variable contractures of more proximal joints and normal intelligence that has_material_basis_in homozygous, compound heterozygous, or heterozygous mutation in the COL6A1 gene on chromosome 21q22.

Ullrich congenital muscular dystrophy 1C

An Ullrich congenital muscular dystrophy characterized by generalized muscle weakness and striking hypermobility of distal joints in conjunction with variable contractures of more proximal joints and normal intelligence that has_material_basis_in homozygous or heterozygous mutation in the COL6A3 gene on chromosome 2q37.

Ullrich congenital muscular dystrophy 1B

An Ullrich congenital muscular dystrophy characterized by generalized muscle weakness and striking hypermobility of distal joints in conjunction with variable contractures of more proximal joints and normal intelligence that has_material_basis_in homozygous, compound heterozygous, or heterozygous mutation in the COL6A2 gene on chromosome 21q22.
