Summaries for Okur-Chung Neurodevelopmental Syndrome

OMIM : 56 Okur-Chung neurodevelopmental syndrome is an autosomal dominant disorder characterized by delayed psychomotor development, intellectual disability with poor speech, behavioral abnormalities, cortical malformations in some patients, and variable dysmorphic facial features. Additional features, including microcephaly, gastrointestinal problems, and low levels of immunoglobulins, may be observed in some patients (Okur et al., 2016). (617062)

MalaCards based summary : Okur-Chung Neurodevelopmental Syndrome, also known as ocnds, is related to hypertelorism and alacrima, achalasia, and mental retardation syndrome. An important gene associated with Okur-Chung Neurodevelopmental Syndrome is CSNK2A1 (Casein Kinase 2 Alpha 1). Affiliated tissues include heart and pituitary, and related phenotypes are failure to thrive and scoliosis

UniProtKB/Swiss-Prot : 73 Okur-Chung neurodevelopmental syndrome: An autosomal dominant neurodevelopmental disorder characterized by developmental delay, intellectual disability, behavioral problems, hypotonia, speech problems, microcephaly, pachygyria and variable dysmorphic features.
