X-Linked Intellectual Disability with Panhypopituitarism



  • The association with mental retardation is also typically present, more frequently in SOX3 duplication than in mutations.[hormones.gr]
  • While widely used sections from the previous edition on cytogenetic technologies and heteromorphisms are retained intact the present volume adds extensive material on copy number variations (polymorphisms detected by microarray analysis), fragile sites[books.google.com]

Developmental Delay
  • Related phenotypes are hypothyroidism and global developmental delay[malacards.org]
  • Global developmental delay MedGen UID: 892935 • Concept ID: C4020875 • Pathologic Function A delay in the achievement of motor or mental milestones in the domains of development of a child, including motor skills, speech and language, cognitive skills[ncbi.nlm.nih.gov]

  • During the first year of life, a mild developmental delay became evident: he sat at 8 months and walked independently at 22 months, while language started at 24 months.[hormones.gr]
  • Disease definition X-linked alpha thalassaemia mental retardation (ATR-X) syndrome in males is associated with profound developmental delay, facial dysmorphism, genital abnormalities and alpha thalassaemia.[orpha.net]
  • Data records in Research Data Australia fall into one of four access types: Open Data that is readily accessible and reusable.[researchdata.ands.org.au]
  • Its proximal breakpoint falls within the SOX3 regulatory region.[uniprot.org]
  • In its most severe form, there is accumulation of MUCOPOLYSACCHARIDES in the SKIN and EDEMA, known as MYXEDEMA. It may be primary or secondary due to other pituitary disease, or hypothalamic dysfunction.[ncbi.nlm.nih.gov]

  • Malforma-tions play a significant health role in over half of the 18 XLIDsyndromes with infant or early childhood lethality.ACKNOWLEDGMENTSThis work was supported in part by NIH grants (NS073854 andHD26202) to CES; MH57840 to RES), the South Carolina[docslide.com.br]
High Arched Palate
  • Variable craniofacial dysmorphism has also been reported, including hypertelorism, epicanthus, synophrys, broad nasal bridge, high-arched palate, long philtrum, cup helices, and coarse facies.[egl-eurofins.com]

  • Although one of these patients exhibited hyperactivity, the absence of ID in some patients 10,17,18 may result from different dosage effects.[hormones.gr]

  • Rapidly consult with trusted authorities thanks to new expert-opinion treatment strategies and recommendations. Zero in on the most relevant and useful references with the aid of a more focused, concise bibliography.[books.google.com]
  • Based on these findings, rhGH treatment was conducted (0.23 mg/kg per week subcutaneously).[hormones.gr]

  • Consult a doctor or other health care professional for diagnosis and treatment of medical conditions. For details see our conditions .[patient.info]


  • Prognosis Although an increased mortality rate in hypopituitary patients is well documented, the actual cause of the increased mortality is not clear. If relevant hormones are adequately replaced, prognosis in hypopituitarism is good.[patient.info]
  • Prognosis A number of individuals with ATR-X are fit and well in their 30s and 40s. The documents contained in this web site are presented for information purposes only.[orpha.net]

  • Etiology This syndrome is X-linked recessive and results from mutations in the ATRX gene. This gene encodes the widely expressed ATRX protein.[orpha.net]
  • The primary anatomicabnormalities, which provide diagnostic clues to the specific syn-drome and its etiology, can be further divided into generalizedskeletal dysplasias and specific focal skeletal malformations(Tables VI and VII).Long bone deficiencies[docslide.com.br]


  • Summary Epidemiology So far, 168 patients have been reported. Clinical description Language is usually very limited. Seizures occur in about one third of the cases.[orpha.net]
  • Epidemiology Taken from the results of one study [ 1 ] : The incidence of hypopituitarism is estimated to be 4·2 per 100,000 per year. The prevalence of hypopituitarism is estimated to be 29-45 per 100,000.[patient.info]

  • Prevention Good obstetric care has reduced the incidence of postpartum hypopituitarism. Radiation therapy that minimises exposure to the pituitary gland reduces incidence and time of onset of hypopituitarism.[patient.info]
