All cases of<unk>  present scalp alopecia, varying degrees of low-set ears and most have a flattened skull. Scalp alopecia has been present in all but one case though it can be asymmetrical or, in a single case, only present on one side. All people with<unk>  also have delayed motor milestones. All people with the<unk>  have malformation of the cerebellum. Certain characteristics are often present in those with<unk>  but are not consistent enough to rule out the<unk>  if they are not present. Reduced eye sensation, or trigeminal anesthesia, is present in about three-quarters of people with<unk> . Malformations of the skull, rotations of the ears, and abnormalities of the face are features that vary widely and cannot be used alone to diagnose<unk>  as these characteristics overlap with some other diseases.<unk>  has been diagnosed as early as 21 weeks with prenatal MRI showing fusion of the cerebellum and later confirmed postnatal with skull and facial abnormalities at six weeks.
