Summaries for Mental Retardation, Autosomal Dominant 22

OMIM : 57 Chromosome 1q43-q44 deletion syndrome is characterized by moderate to severe mental retardation, limited or no speech, and variable but characteristic facial features, including round face, prominent forehead, flat nasal bridge, hypertelorism, epicanthal folds, and low-set ears. Other features may include hypotonia, poor growth, microcephaly, agenesis of the corpus callosum, and seizures. The phenotype is variable, and not all features are observed in all patients, which may be explained in some cases by incomplete penetrance or variable expressivity (summary by Ballif et al., 2012). Patients with autosomal dominant mental retardation-22 have a phenotype similar to that in patients with chromosome 1q43-q44 deletion syndrome (de Munnik et al., 2014). (612337)

MalaCards based summary : Mental Retardation, Autosomal Dominant 22, is also known as mrd22, and has symptoms including seizures An important gene associated with Mental Retardation, Autosomal Dominant 22 is ZBTB18 (Zinc Finger And BTB Domain Containing 18). Related phenotypes are short stature and thin vermilion border

UniProtKB/Swiss-Prot : 75 Mental retardation, autosomal dominant 22: A disorder characterized by significantly below average general intellectual functioning associated with impairments in adaptive behavior and manifested during the developmental period. Additional MRD22 patients have limited or no speech, and variable but characteristic facial features, including round face, prominent forehead, flat nasal bridge, hypertelorism, epicanthal folds, and low- set ears. Other features may include hypotonia, poor growth, microcephaly, agenesis of the corpus callosum, and seizures.

Disease Ontology : 12 An autosomal dominant non-syndromic intellectual disability that has material basis in an autosomal dominant mutation of ZBTB18 on chromosome 1q44.
