Summaries for Mental Retardation, X-Linked, Syndromic, Christianson Type

OMIM® : 57 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 (summary by Schroer et al., 2010 and Pescosolido et al., 2014). (300243) (Updated 20-May-2021)

MalaCards based summary : Mental Retardation, X-Linked, Syndromic, Christianson Type, also known as mental retardation microcephaly epilepsy and ataxia syndrome, is related to christianson syndrome and microcephaly, and has symptoms including ataxia, ophthalmoplegia and sleep disturbances. An important gene associated with Mental Retardation, X-Linked, Syndromic, Christianson Type is SLC9A6 (Solute Carrier Family 9 Member A6). Affiliated tissues include eye, cerebellum and skeletal muscle, and related phenotypes are dysphagia and microcephaly

UniProtKB/Swiss-Prot : 72 Mental retardation, X-linked, syndromic, Christianson type: A syndrome characterized by profound mental retardation, epilepsy, ataxia, and microcephaly. It shows phenotypic overlap with Angelman syndrome.
