<unk>  (also called Garcia-Lurie syndrome,<unk> , and<unk> -atelencephaly syndrome) is an extremely rare congenital disorder characterized by the absence of the embryonic forebrain. Because the prosencephalon gives way to the cerebral cortex, survival with<unk>  is not possible outside utero. The external symptoms are similar to holoprosencephaly, a related disorder, including a smaller than normal head (microcephaly), small eyeballs (microphthalmia), a small mouth (microstomia), anal atresia (no anus), and abnormalities of the external genitalia, radius, nostrils, and pharynx (throat).
