\Head finding (finding)\Finding of head circumference (finding)\Occipitofrontal circumference of between two and equal to or greater than five standard deviations below the mean for age, sex, and gestation.\A rare neurological disorder characterized by a reduced head circumference at birth with no gross anomalies of brain structure. It can be an isolated finding or it can be associated with seizures, developmental delay, intellectual disability, balance disturbances, hearing loss or vision problems.\A rare genetic neurologic disease with characteristics of congenital microcephaly, severe early-onset epileptic encephalopathy (manifesting as intractable, myoclonic and/or tonic-clonic seizures), permanent neonatal, insulin-dependent diabetes mellitus and severe global developmental delay.
