Most people with Kabuki syndrome have mild to moderate intellectual disability, although this varies considerably. Early speech and language delay is common and some language-related difficulties usually persist.Other medical problems may also be present. Congenital heart defects are common. Skeletal abnormalities may include a short and curved pinky finger (clinodactyly); spine abnormalities; and joint dislocations. Affected people often have weak muscle tone (hypotonia); feeding difficulties; seizures; and a small head size (microcephaly). Vision and hearing problems may also be present. Some affected children are more susceptible to infections, particularly ear infections.
The Human Phenotype Ontology (HPO) provides the following list of features that have been reported in people with this condition. Much of the information in the HPO comes from Orphanet, a European rare disease database. If available, the list includes a rough estimate of how common a feature is (its frequency). Frequencies are based on a specific study and may not be representative of all studies. You can use the MedlinePlus Medical Dictionary for definitions of the terms below.
