What are the other Names for this Condition? (Also known as/Synonyms)

• Pierre Robin Syndrome, Faciodigital Anomaly
• Robin Sequence with Facial and Digital Anomalies

What is Chitayat Meunier Hodgkinson Syndrome? (Definition/Background Information)

• Chitayat Meunier Hodgkinson Syndrome is characterised by the association of Pierre Robin sequence (retrognathia, cleft palate and glossoptosis) with facial dysmorphism (high forehead with frontal bossing) and digital anomalies (tapering fingers, hyperconvex nails, clinodactyly of the fifth fingers and short distal phalanges, finger-like thumbs and easily subluxated first metacarpophalangeal joints)
• Growth and mental development were normal
• Transmission appears to be X-linked recessive. It has been described in two half-brothers born to the same mother

Who gets Chitayat Meunier Hodgkinson Syndrome? (Age and Sex Distribution)

• Chitayat Meunier Hodgkinson Syndrome is a rare congenital disorder. The presentation of symptoms may occur at birth
• Males and females may be affected; however, all the reported cases have been observed in male children (since the condition may be X-linked)
• Worldwide, individuals of all racial and ethnic groups may be affected

What are the Risk Factors for Chitayat Meunier Hodgkinson Syndrome? (Predisposing Factors)

• A positive family history may be an important risk factor, since Chitayat Meunier Hodgkinson Syndrome can be reportedly inherited
• Currently, no other risk factors have been clearly identified for the syndrome

It is important to note that having a risk factor does not mean that one will get the condition. A risk factor increases one’s chances of getting a condition compared to an individual without the risk factors. Some risk factors are more important than others.

Also, not having a risk factor does not mean that an individual will not get the condition. It is always important to discuss the effect of risk factors with your healthcare provider.
