Affymetrix SNP array data for family UNK-129-KW with multiple patients suffering from a lethal form of a primary immunodeficiency.

ABSTRACT: Linkage analysis and Copy Number Variation were performed on DNA isolated from the peripheral blood of the 2 affected male patients, their unaffected parents, and their unaffected 4 male siblings, according to the manufacturer's description. This allowed to narrow down the region of homozygosity specifice to the patients. This approach, in combination with Whole Exome sequencing performed on DNA isolated from the 2 affected patients and their mother, allowed to identify a homozygous missense mutation in the base excision repair enzyme NEIL3 that reduced its enzymatic activity, and a homozygous duplication of exons 48-53 of the LPS Responsive Beige-Like Anchor Protein LRBA that abolished protein expression. Homozygozity mapping was performed with the Affymetrix genome-wide human single nucleotide polymorphism (SNP) array 6.0, and analyzed with Birdsuite version 1.4 and PLINK version 1.07.

Cytogenetics 2.7M and Cytoscan HD 2.8M Microarrays in autistic families in the Lebanese population

Project description:Autism spectrum disorder (ASD) affects these core domains: ritualistic-repetitive behaviors, impaired social interaction, and deficits in non-verbal communication/language development. Although ASD is heritable, its extreme heterogeneity defies genetic analyses. A number of ASD susceptibility genes have been identified. The Lebanese population is ideal for uncovering recessive genes because of a high rate of shared ancestry, consanguineous marriages, and high number of offspring per family. We recruited 36 ASD families (ASD: 37, unaffected parents: 36, unaffected siblings: 33). Cytogenetics 2.7M Microarrays/CytoScanâ¢ HD arrays allowed mapping of homozygous regions of the genome.

Transcription profiling of micro-RNA genes in human papillary thyroid carcinoma

Project description:We show that numerous miRNAs are transcriptionally up-regulated in papillary thyroid carcinoma (PTC) tumors compared with unaffected thyroid tissue. Among the predicted target genes of the three most upregulated miRNAs (miRs 221, 222 and 146b), only less than 15% showed significant downexpression in transcript level between tumor and unaffected tissue. The KIT gene which is known to be downregulated by miRNAs 221 and 222 displayed dramatic loss of transcript and protein in those tumors that had abundant mir-221, mir-222, and mir-146b transcript. Experiment Overall Design: Total RNA was extracted from paired tumor and normal thyroid tissues from 9 PTC patients. The same set samples were applied to Custom miRNA microarray chips (OSU_CCC version 2.0) and Affymetrix HG-U133 plus 2 chips.

PWC dataset for genome-wide association study of modifiers of risk of canine degenerative myelopathy in dogs homozygous for SOD1 mutation

Project description:Degenerative myelopathy (DM) is a canine disease very similar to amyotrophic lateral sclerosis (ALS) in humans. We previously showed that DM is a promising model for ALS, as genome-wide association identified a mutation in SOD1, a known ALS gene. In this study, we identify a modifier gene, SP110, which strongly affects overall disease risk and age-of-onset in Pembroke Welsh corgis at risk of DM. Dissecting the complex genetics of this disease in a model organism may lead to new insights about risk and progression in both canine and human patients. 15 DM-affected and 31 unaffected PWC homozygous for SOD1 mutation genotyped using the Illumina CanineHD array (~170,000 SNPs genomewide)

Genotyping of SNP array in individuals with San ancestry in southeastern Africa

Project description:Only a few scattered groups with oral traditions of Khoe-San hunter-gatherer ancestry remain in southeastern Africa. We investigate genomic variation of remaining individuals from two South African groups with oral histories connecting them to eastern San groups, i.e., the San from Lake Chrissie and the Duma San of the uKhahlamba-Drakensberg. Using ~2.2 million genetic markers, combined with comparative published datasets, we show that the Lake Chrissie San have genetic ancestry from both Khoe-San (likely the ||Xegwi San) and Bantu-speakers. Specifically, we found that the Lake Chrissie San are closely related to current southern San groups (i.e. the Karretjie People). Duma San individuals, on the other hand, were genetically similar to southeastern Bantu speakers from South Africa. Samples were genotyped on the Illumina Omni2.5M (HumanOmni25-8v1-2_A1) SNP chip. Results were analyzed using the software GenomeStudio 2011.1 and the data were exported to Plink format, aligned to Human Genome build version 37.

Loss of soluble guanylate cyclase, the major nitric oxide receptor, leads to moyamoya and achalasia.

Project description:Background: Moyamoya is a cerebrovascular condition of unknown mechanism characterized by a progressive stenosis of the terminal part of the internal carotid arteries (ICA) and the compensatory development of abnormal “moyamoya” vessels. It leads to ischemic and hemorrhagic stroke. We describe a novel autosomal recessive disease leading to severe moyamoya and early onset achalasia and report its cause in 3 unrelated families. Methods: We used a combination of genetic linkage and exome sequencing in 2 consanguineous to identify rare shared variants. Sanger sequencing of GUCY1A3, the sole gene mutated in both families, was then conducted in the third family. Platelets from one of the patients and controls were used to carry out functional studies. Results: Homozygous mutations of GUCY1A3 gene encoding the alpha1 subunit of soluble guanylate cyclase (sGC), the major receptor for Nitric Oxide (NO), were identified in all 3 families. Platelet analysis showed a complete loss of the mutated protein and showed an unexpected stimulatory role of sGC within platelets. Conclusion: The NO/sGC/cGMP pathway is a major pathway controlling vascular smooth muscle (VSMC) relaxation, vascular tone and vascular remodeling. Our data suggest that alterations of this pathway may lead to an abnormal vascular remodeling process in sensitive vascular areas with low blood A total of 17 samples (8 affected and 9 unaffected) were used for this study. Linkage analysis was performed in a single informative consanguine family composed of 2 unaffected parents, 4 affected siblings and 3 unaffected siblings. Two affected samples in two different families were used for the exome sequencing analysis and results were compared to 20 control exomes (in-house exomes from IntegraGen, Evry, France) and 8 HapMap exomes. All samples were used for Sanger Sequencing confirmation.
