Cardiospondylocarpofacial syndrome
(Redirected from Mitral regurgitation deafness skeletal anomalies)
Cardiospondylocarpofacial syndrome is a very rare genetic disorder which is characterized by cardiac, digital, osseous anomalies with facial dysmorphisms. Cardiospondylocarpofacial syndrome is believed to be caused by autosomal dominant mutations of the MAP3K7 gene.[3]

|---|---|
| Other names | Forney syndrome, Forney-Robinson-Pascoe syndrome, Mitral regurgitation-deafness-skeletal anomalies syndrome, Mitral regurgitation-hearing loss-skeletal anomalies syndrome. |
 | |
| Cardiospondylocarpofacial syndrome has an autosomal dominant form of inheritance. | |
| Symptoms | Vertebral anomalies, brachydactyly, conductive hearing loss, high palate, mitral regurgitation, mitral valve prolapse, short stature, short palms, and carpal bone synostosis.[1] |
| Causes | Autosomal dominant mutations of the MAP3K7 gene.[1] |
| Diagnostic method | Genetic testing. |
| Frequency | Only 12 cases worldwide.[2] |
Signs and symptoms
editCardiospondylocarpofacial syndrome manifests itself in many different areas of the body. It causes heart defects, multiple congenital anomalies, and dysmorphic features. The following is a list of the symptoms most commonly exhibited:[1]
- Variable vertebral anomalies
- Brachydactyly
- Conductive hearing loss
- High palate
- Mitral regurgitation
- Mitral valve prolapse
- Short stature, nearing dwarfism
- Short palms
- Carpal bone synostosis
Less common symptoms include:
- Failure for permanent teeth to erupt
- Teeth misalignment
- Horseshoe kidney
- Dentition anomalies
- Ocular anomalies
- Nostril anteversion
- Epiphysis in the shape of a cone
- Decreased testes size (males)
- Skeletal maturation delay
- Feeding difficulties
- Freckles
- Apple cheeks
- Gastroesophageal reflux
- Hypertelorism
- Joint hypermobility
- Long philtrum
- Rotated ears
- Pseudoepiphyses
- High frequency of middle ear infections
- Rib synostosis
- Scoliosis
- Small foot
- Strabismus
- Tarsal synostosis
- Telecanthus
- Upslanted palpebral fissures
- Broad nasal bridge
- Vesicoureteral reflux
Causes
editIt is caused by autosomal dominant mutations of the MAP3K7 gene in the long arm of chromosome 6.[4][3]
Epidemiology
editOnly 12 cases worldwide have been described in medical literature.[2]
