Facial features in children with the 22q11 deletion syndrome

Abstract

Aim: To find a pattern of the most typical facial features in children with the 22q11 deletion syndrome, which could serve as an aid in identifying patients with the syndrome.

Methods: In 80 children and adolescents with the 22q11 deletion syndrome, three investigators evaluated the facial features separately using frontal and profile photographs. A patient was considered to have a given feature if at least two of the evaluators agreed.

Results: The most common facial features found in at least 50% of the patients were malar flatness, fullness of eyelids (hooded eyelids), broad nasal bridge/tubular nose, broad/round nasal tip, round ears, thick/overfolded helix and slightly low-set ears. These were also the most common features when all agreed, although a considerable variation in the assessment by the three evaluators was observed.

Conclusions: The 22q11 deletion syndrome is a differential diagnosis in children with a variety of symptoms and signs including congenital malformations, developmental delay and speech abnormalities. Almost all children with the syndrome show a characteristic pattern of minor facial variants, which can be difficult to recognise, unless specifically looked for. A systematic evaluation of facial features might help in identifying children with the syndrome.
