Summaries for Mental Retardation, Autosomal Recessive 44

About this section
UniProtKB/Swiss-Prot : 75 Mental retardation, autosomal recessive 44: A disorder characterized by significantly below average general intellectual functioning associated with impairments in adaptive behavior and manifested during the developmental period. MRT44 manifestations include mild to severe cognitive impairment, delayed psychomotor development, seizures in some patients, and dysmorphic features.

MalaCards based summary : Mental Retardation, Autosomal Recessive 44, is also known as mrt44. An important gene associated with Mental Retardation, Autosomal Recessive 44 is METTL23 (Methyltransferase Like 23). Affiliated tissues include eye, skin and bone, and related phenotypes are intellectual disability and seizures
