An autosomal recessive congenital disorder affecting multiple systems with features of a ciliopathy. Affected individuals typically have some type of intestinal atresia, variable ocular abnormalities, microcephaly, and sometimes involvement of other systems, including renal and cardiac. In some cases, the condition is lethal in early life, whereas other patients show normal survival with or without mild cognitive impairment (summary by Filges et al., 2016).
