Presentation
Cardiac anomalies and paralysis of the vocal chords may also be present. Six cases have been reported so far. Transmission is thought to be autosomal recessive. [orpha.net]
Additional suspicion should be present for patients from other ethnic groups that may have sporadic disease. [eyewiki.aao.org]
Each diagnosis includes clinical presentation(s) of affected patients, the best sequences for imaging analysis, expected imaging sequences (in both common and uncommon presentations), and imaging examples of key features. [books.google.com]

Common features include a cleft in the lip or palate, abnormal facial features, limb or skeletal abnormalities, intellectual disability and delayed growth and development. [centogene.com]
Both children showed develop-ment functioning at an infant level, raising the possibi-lity of greater disability secondary to hypoxic braininjury. [docslide.com.br]
