17q11 Microdeletion Syndrome

Neurofibromatosis Type 1


  • Here, we present another patient with 17q11.2 duplication and no signs of neurofibromatosis type 1, identified by array-CGH. We compared clinical features and genetic data with those of previously reported patients with 17q11.2 microduplications.[ncbi.nlm.nih.gov]
  • We present a 3 year old girl, born to consanguineous Sephardic Jewish parents, who are known carriers of Sandhoff disease, for which prenatal diagnosis was performed with normal results.[ashg.org]
  • Springer, ١٧‏/١١‏/٢٠١٦ - 142 من الصفحات This book presents a long-term study in genetic isolates of indigenous small ethnics of Dagestan, located in the North-East part of Caucasus in Russia.[books.google.com]
  • Case presentation Here we reported a patient carrying a novel de novo deletion at 17q11.2 adjacent to NF1 gene, who presented with developmental delay, short stature, postnatal microcephaly, underweight and dysmorphic features including flat facial profile[molecularcytogenetics.biomedcentral.com]
  • If present, they should lead to the suspicion of an NF1 microdeletion syndrome.[karger.com]
  • The book also discusses how insights into the regulation of apoptosome may be exploited for designing new drugs aimed at interfere with a plethora of pathogenetic processes involved in human diseases.[books.google.de]
  • Key Features: Provides thorough information on understanding functional neuroanatomy and development, and on using functional neuroimaging Highlights clinical practice issues, such as legal and ethical decision-making, dealing with child abuse and neglect[books.google.de]


  • Clinical Testing and Workup In the past, a specific chromosomal study known as G-band analysis, which demonstrates missing (deleted) material on chromosome 17p, was used to help obtain a diagnosis of SMS.[rarediseases.org]


  • The authors emphasize novel translational approaches that are rapidly moving from the laboratory bench top to the patient's bedside for the future treatment of diseases associated with apoptosis.[books.google.de]
  • It focuses on the genetics and molecular biology underlying these diseases, but also covers their clinical features, diagnosis and treatment, stressing the need for interdisciplinary medical care.[books.google.de]


  • The variable expressivity of the disease makes it challenging to establish genotype–phenotype correlations, which also affects prognosis and counselling. We here describe a 3-year-old NF1 patient with an atypical deletion and a complex phenotype.[moh-it.pure.elsevier.com]
  • Diagnosis - Neurofibromatosis type 1 Prognosis - Neurofibromatosis type 1 Treatment - Neurofibromatosis type 1 There is no cure for the disorder itself.[checkorphan.org]
  • Prognosis Because of the highly variable nature of SMS, it is impossible to generalize about prognosis for individual cases.[rarediseases.org]


  • Etiology Germline and mosaic microdeletions of the NF1 gene and its flanking regions caused by non-allelic homologous recombination are reported in patients with this disorder. Most occur de novo.[rarediseases.info.nih.gov]

  • This new edition contains several chapters on the associated problems of autism, such as intellectual disability, epilepsy, tics, eating disorders and sleep problems, as well as a chapter on epidemiology that documents the historical increase in autism[books.google.de]
  • Epidemiology The prevalence of 17q11 microdeletion syndrome is not known. About 5% of NF1 cases are reported to have deletions of the entire NF1 gene. More than 170 affected patients have been reported to date.[rarediseases.info.nih.gov]
