It has been classified into 4 types based on the severity of associated brain and facial malformations. The most severe variety called alobar HPE is generally associated with major cranio-facial anomalies such as cyclopia, ethmocephaly, cebocephaly, or cleft-lip/palate. Significant etiological heterogeneity exists in HPE and includes both genetic and environmental causes. Maternal diabetes is a well-established environmental factor with a significant increased risk for HPE. We report on a Saudi Arab girl born to a diabetic mother, with the alobar type of holoprosencephaly, associated with very minimal cranio-facial defects. However, she displayed several other congenital malformations. In addition, she was diagnosed with cystic fibrosis. Simultaneous occurrence of cystic fibrosis and congenital anomalies has been rare.
