Presentation
Syndactyly of the fingers is sometimes present as well. Clefting of the soft and hard palates is commonly present and a few patients have had joint contractures. Hearing loss of all types has been reported. Mental development seems to be normal. [disorders.eyes.arizona.edu]
Type 3: In Klein-Waardenburg syndrome or pseudo-Waardenburg syndrome, dystopia canthorum is not present, but one-sided ptosis of the upper eyelid and upper limb anomalies are present. [emedicine.medscape.com]
Affected subjects generally present a very similar behaviour with sociable and good natured disposition. [jmg.bmj.com]

Most patients also have gastrointestinal and mild ocular abnormalities, as well as behavioral problems (summary by DeSanto et al., 2015 ). [mendelian.co]
