Affymetrix 6.0 study of sporadic motor neuron disease patients and controls.


ABSTRACT: This data was divided into three experiment sets: 1. A somatic study of sporadic motor neuron disease (SMND) brain samples that were compared to the blood from the same individual, normal control brains and disease control brans (Parkinson Disease patients); 2. A twin study comparing blood and other tissue samples from twins that were discordant for MND, concordant for MND and control twins and 3. A trio study of blood samples MND patients compared to their unaffected parents. Study 1: 36 sporadic motor neuron disease brain (lateral frontal cortex, Brodmann area 46), 34 matched sporadic motor neuron disease blood, 26 control brain (lateral frontal cortex, Brodmann area 46), 9 Parkinson Disease brain (disease controls, lateral frontal cortex, Brodmann area 46). Study 2 and study 3: 52 twin or trio blood, 4 twin hair, 1 twin sperm. 2 replicate twin blood and 1 replicate trio blood repeated at a different time. External control blood from Coriell GM15510 and GM10851.

MicroRNAs are involved in post-transcriptional down-regulation of gene expression. Variations in miRNA genes can severely affect downstream-regulated genes and their pathways. However, population-specific burden of CNVs on miRNA genes and the complexities created towards the phenotype is not known. From a total of 44109 CNVs investigated from 1715 individuals across 12 populations using high-throughput arrays, 4007 miRNA-CNVs (∼ 9%) consisting 6542 (∼ 5%) miRNA genes with a total of 333 (∼ 5%) s  ...[more]
