Tracy Lester (Genetics laboratory, Oxford UK)

Red List (low evidence)

Christianson syndrome is an X-linked neurodevelopmental and progressive mental retardation syndrome characterized by microcephaly, impaired ocular movements, severe global developmental delay, developmental regression, hypotonia, abnormal movements, and early-onset seizures of variable types. Female carriers may be mildly affected - developmental disorder with early onset - red
