Metaphyseal chondrodysplasia, Spahr type (MCDS) is a rare genetic disorder that affects the development of bones and joints. It is characterized by short stature, skeletal abnormalities, and joint laxity. Affected individuals may also have facial dysmorphism, hearing loss, and intellectual disability. The condition is caused by mutations in the COL2A1 gene and is inherited in an autosomal dominant manner.

The symptoms of Metaphyseal chondrodysplasia, Spahr type include short stature, short limbs, a broad chest, a prominent forehead, a short neck, and a wide, short skull. Other features may include a short nose, a wide mouth, a high-arched palate, and a protruding lower jaw. Affected individuals may also have a short, broad thumb and a short, broad big toe. Skeletal abnormalities may include a short, broad femur, a short, broad humerus, and a short, broad radius. Other Skeletal abnormalities may include a short, broad pelvis, a short, broad ribs, and a short, broad vertebrae.

Metaphyseal chondrodysplasia, Spahr type is caused by a mutation in the COL10A1 gene. This gene provides instructions for making a protein called type X collagen, which is important for the normal development of bones and cartilage. Mutations in the COL10A1 gene lead to the production of an abnormal type X collagen protein, which disrupts the normal development of bones and cartilage, resulting in the signs and symptoms of Metaphyseal chondrodysplasia, Spahr type.

The treatments for Metaphyseal chondrodysplasia, Spahr type, vary depending on the severity of the condition and the individual patient. Generally, treatment focuses on managing the symptoms and complications associated with the condition. This may include physical therapy to help improve mobility, orthopedic surgery to correct skeletal deformities, and medications to help manage pain. In some cases, growth hormone therapy may be recommended to help improve growth and development. Additionally, genetic counseling may be recommended to help families understand the condition and its implications.
