How is Roberts syndrome diagnosed?

The diagnosis of Roberts syndrome is suspected in individuals with the following:
  • Prenatal growth delay ranging from mild to severe. Average birth length and weight is typically below the third percentile in most affected infants.
  • Limb malformations including bilateral, symmetric tetraphocomelia (phocomelia of all 4 limbs) or hypomelia (underdevelopment of the limbs) caused by mesomelic shortening (shortening of the middle part of the limb). Upper limbs are typically more severely affected than lower limbs. Other limb malformations include oligodactyly with thumb aplasia (lack of formation) or hypoplasia (underdevelopment), syndactyly, clinodactyly, and elbow and knee flexion contractures (inability to fully straighten the arms and legs).
  • Craniofacial abnormalities including bilateral cleft lip and/or palate, micrognathia (small jaw), hypertelorism (widely-spaced eyes), exophthalmos (bulging eyes), downslanting palpebral fissures, malar hypoplasia (underdeveloped cheek bones), hypoplastic nasal alae, and ear malformations.
The diagnosis of Roberts syndrome relies on a cytogenetic blood test of individuals with the above features. Cytogenetic testing would show the characteristic chromosomal abnormalities that are present in individuals with the condition.[1]
