Summaries for Raynaud-Claes Syndrome

OMIM® : 57 Raynaud-Claes syndrome is an X-linked intellectual developmental disorder characterized by borderline to severe intellectual disability and impaired language development. Additional features include behavioral problems, psychiatric disorders, seizures (variable forms), progressive ataxia, brain abnormalities, and facial dysmorphisms. Some heterozygous females are unaffected, whereas others are affected with a severity spectrum similar to that seen in males (summary by Palmer et al. (2018)). (300114) (Updated 05-Apr-2021)

MalaCards based summary : Raynaud-Claes Syndrome, also known as mental retardation, x-linked 49, is related to syndromic x-linked intellectual disability cabezas type and hypotonia. An important gene associated with Raynaud-Claes Syndrome is CLCN4 (Chloride Voltage-Gated Channel 4). Related phenotypes are scoliosis and behavioral abnormality

Disease Ontology : 12 A syndromic X-linked intellectual disability characterized by borderline to severe intellectual disability, impaired language development, and variable additional features including; behavioral problems, psychiatric disorders, seizures, progressive ataxia, brain abnormalities, and facial dysmorphisms that has material basis in heterozygous or hemizygous mutation in CLCN4 on chromosome Xp22.2.

UniProtKB/Swiss-Prot : 72 Raynaud-Claes syndrome: An X-linked syndrome characterized by borderline to severe intellectual disability and impaired language development. Additional features include behavioral problems, psychiatric disorders, seizures, progressive ataxia, brain abnormalities, and facial dysmorphisms.
