Summaries for Alpha-Thalassemia/mental Retardation Syndrome

UniProtKB/Swiss-Prot : 66 Alpha-thalassemia mental retardation syndrome, X-linked: A disorder characterized by severe psychomotor retardation, facial dysmorphism, urogenital abnormalities, and alpha-thalassemia. An essential phenotypic trait are hemoglobin H erythrocyte inclusions.

MalaCards based summary : Alpha-Thalassemia/mental Retardation Syndrome, also known as atr-x syndrome, is related to mental retardation-hypotonic facies syndrome, x-linked and mental retardation, x-linked, syndromic 15, and has symptoms including constipation, seizures and joint stiffness. An important gene associated with Alpha-Thalassemia/mental Retardation Syndrome is ATRX (ATRX, Chromatin Remodeler), and among its related pathways/superpathways are Chks in Checkpoint Regulation and DNA Damage. Affiliated tissues include kidney and tongue, and related phenotypes are Increased shRNA abundance (Z-score > 2) and behavior/neurological
