Summaries for Mental Retardation, Autosomal Recessive 61

UniProtKB/Swiss-Prot : 75 Mental retardation, autosomal recessive 61: A form of mental retardation, a disorder characterized by significantly below average general intellectual functioning associated with impairments in adaptive behavior and manifested during the developmental period. MRT61 patients manifest delayed psychomotor development, moderate to severe intellectual disability, and variable dysmorphic facial features. Refractory seizures and brain abnormalities are present in severely affected patients.

MalaCards based summary : Mental Retardation, Autosomal Recessive 61, is also known as alwadei syndrome. An important gene associated with Mental Retardation, Autosomal Recessive 61 is RUSC2 (RUN And SH3 Domain Containing 2). Affiliated tissues include brain.

OMIM : 57 MRT61 is an autosomal recessive neurodevelopmental disorder characterized by delayed psychomotor development, moderate to severe intellectual disability, and variable dysmorphic facial features. More severely affected patients may develop refractory seizures and have brain abnormalities, including hypoplasia of the corpus callosum (summary by Alwadei et al., 2016). (617773)
