The main features of Hanhart syndrome include a short, incompletely developed tongue (hypoglossia); absent or partially missing fingers and/or toes (hypodactylia); malformed arms and/or legs (peromelia); and an extremely small jaw (micrognathia). Retrognathia (receding jaw) is also a common feature of Hanhart syndrome. Other features that have been reported include hypodontia (missing teeth) and the absence of major salivary glands. The limb abnormalities in individuals with Hanhart syndrome have ranged from shortened fingers or toes and oligodactyly (missing fingers or toes) to more severe abnormalities such as absent or malformed limbs. In an affected individual, any limb may be affected. The severity of the physical abnormalities associated with Hanhart syndrome varies greatly among affected individuals, and children with this disorder often have some, but not all, of the symptoms.
