Autism is a common neurodevelopmental disorder of complex genetic etiology. Rett syndrome, an X-linked dominant disorder caused by MECP2 mutations, and Angelman syndrome, an imprinted disorder caused by maternal 15q11-q13 or UBE3A deficiency, have phenotypic and genetic overlap with autism. MECP2 encodes methyl-CpG-binding protein 2 that acts as a transcriptional repressor for methylated gene c...
Prader-Willi syndrome (PWS) and Angelman syndrome (AS) are clinically distinct complex disorders mapped to chromosome 15q11-q13. They both have characteristic neurologic, developmental, and behavioral phenotypes plus other structural and functional abnormalities. However, the cognitive and neurologic impairment is more severe in AS, including seizures and ataxia. The behavioral and endocrine di...
Prader-Willi syndrome (PWS) and Angelman syndrome are neurogenetic disorders caused by the lack of a paternal or a maternal contribution from human chromosome 15q11-q13, respectively. Deletions in the transcription unit of the imprinted SNRPN gene have been found in patients who have PWS or Angelman syndrome because of a parental imprint switch failure in this chromosomal domain. It has been su...
Myelodysplastic syndromes and acute myeloid leukemia with an isodicentric X chromosome [idic(X)(q13)] occur in elderly women and frequently display ringed sideroblasts. Because of the rarity of idic(X)(q13), little is known about its formation, whether a fusion gene is generated, and patterns of additional aberrations. We here present an SNP array study of 14 idic(X)-positive myeloid malignanci...
Abstract Wineries in the “old world” export almost 40% of their production. This study analyzes influence vertical and horizontal networks on performance. We draw a sample 183 Spanish wineries examine main independent variables using two-step Heckman model. find positive effects and—at somewhat lower level—downstream (JEL Classifications: L66, M16, Q13)
Sleep disorder in Angelman syndrome: causes, mechanisms and methods of correction. Literature review
Sleep disorder is one of the prominent manifestations Angelman syndrome. The exact causes are unknown and methods correction difficult. literature review devoted to studies pathogenesis sleep disorders in syndrome (the effects gene function 15q11–q13 deletion, findings polysomnography, video-EEG monitoring, laboratory data), on basis which recommendations for dyssomnia, including behavioral the...
در این پژوهش اثر تنش اکسیداتیو (oxidative stress) ناشی از تنش خشکی و پیری بر میزان کلروفیل a، کلروفیل b، کاروتنوئیدها، پروتئین زیر واحد بزرگ آنزیم روبیسکو (rbcl)، آنزیمهای آنتی اکسیدان شامل سوپراکسید دیسموتاز (sod) و آسکوربات پراکسیداز (apx) در مراحل شروع باروری، پرشدن دانه، شیری شدن ثانویه و خمیری نرم در شرایط مزرعه ای در دو ژنوتیپ جو با عملکرد متفاوت (ژنوتیپ q13 با عملکرد 1390 کیلوگرم در هکتا...
We report two cases of acute myeloid leukemia (M1 and M5B subtypes) with a similar translocation, t(3;11)(q21;q13). We discuss the involvement of these breakpoints in acute leukemia and their putative clinical implications.
The recessive oncogene cylindromatosis (CYLD) mapping on 16q12-q13 is generally implicated in familial cylindromatosis, whereas a gene region for multiple familial trichoepithelioma has been assigned to 9p21. Markers from both chromosome intervals were subjected to linkage analysis in a large family with multiple hereditary trichoepithelioma (TE) from Algeria. Linkage to 9p21 was excluded, wher...
Refractory anaemia with ring sideroblasts and marked thrombocytosis (RARS-T) is a provisional entity in the World Health Organization (WHO) classification. It displays features characteristic of both myelodysplastic syndrome and myeloproliferative neoplasia plus ring sideroblasts ≥15% and marked thrombocytosis. Most patients with RARS-T show a normal karyotype. We report a 76-year-old woman dia...
