Weiss-Kruszka syndrome (WSKA) is an autosomal dominant multiple congenital anomaly syndrome characterized by variable but usually mild global developmental delay and common craniofacial abnormalities, including ptosis, abnormal head shape, downslanting palpebral fissures, epicanthal folds, arched eyebrows, and short upturned nose. Many patients have hypotonia and feeding difficulties. A few patients show agenesis of the corpus callosum on brain imaging. Most cases occur sporadically, but there are rare familial cases that show highly variable expressivity in the phenotypic manifestations (summary by Kruszka et al., 2019).  http://www.omim.org/entry/618619
