BACKGROUND Here we describe a new case of partial distal 10q trisomy in a 6-year-old Iranian girl from healthy parents with mental, growth, and psychomotor retardations. METHODS Additional clinical features include dysmorphic craniofacial features, microcephaly, bilateral hydronephrosis without heart problems, small and rotated low-set ears, bow-shaped mouth, abnormal teeth, short neck, and a...
Glioblastomas are regarded as the most common malignant brain tumours with great morphological and genetical heterogeneity. They comprise 12% to 15% of all intracranial tumours, with its peak observed in the 8th decade of life. The five-year survival is only 5%. Primary glioblastomas are more common in elders while secondary glioblastomas mostly involve younger people. Based upon gene expressio...
Acquired homozygosity in the form of segmental acquired uniparental disomy (aUPD) has been described in follicular lymphoma (FL) and is usually due to mitotic recombination. SNP array analysis was performed with the use of the Affymetrix 10K 2.0 Gene-chip array on DNA from 185 diagnostic FL patients to assess the prognostic relevance of aUPD. Genetic abnormalities were detected in 118 (65%) of ...
Granular cell astrocytoma (GCA) is a rare type of malignant brain tumor with distinct morphologic features and aggressive clinical behavior. Almost all GCAs occur in the cerebral hemispheres. It is characterized by a prominent component of bland-looking granular cells. The tumor cells are usually positive for glial fibrillary acidic protein, S100, CD68, and epithelial membrane antigen. The most...
The apolipoprotein E (APOE) gene has been consistently shown to be a major genetic risk factor; however, all cases of Alzheimer's disease (AD) cannot be attributed to the epsilon4 variant of APOE, because about half of AD patients have the APOE-epsilon3*3 genotype. To identify an additional genetic risk factor(s), we performed large-scale single nucleotide polymorphism (SNP)-based association a...
Alzheimer's disease (AD) is the most common cause of dementia. It is characterized by beta-amyloid (A beta) plaques, neurofibrillary tangles and the degeneration of specifically vulnerable brain neurons. We observed high expression of the cholesterol 25-hydroxylase (CH25H) gene in specifically vulnerable brain regions of AD patients. CH25H maps to a region within 10q23 that has been previously ...
