Exome Sequencing Reveals VCP Mutations as a Cause of Familial ALS

Reads0

TLDR
Exome sequencing data broaden the phenotype of IBMPFD to include motor neuron degeneration, suggest that VCP mutations may account for ∼1%-2% of familial ALS, and provide evidence directly implicating defects in the ubiquitination/protein degradation pathway in motor neurons degeneration.

A hexanucleotide repeat expansion in C9ORF72 is the cause of chromosome 9p21-linked ALS-FTD

Alan E. Renton, +85 more
- 20 Oct 2011 - 
TL;DR: The chromosome 9p21 amyotrophic lateral sclerosis-frontotemporal dementia (ALS-FTD) locus contains one of the last major unidentified autosomal-dominant genes underlying these common neurodegenerative diseases, and a large hexanucleotide repeat expansion in the first intron of C9ORF72 is shown.

Exome sequencing as a tool for Mendelian disease gene discovery

TL;DR: Experimental and analytical approaches relating to exome sequencing have established a rich framework for discovering the genes underlying unsolved Mendelian disorders and set the stage for applying exome and whole-genome sequencing to facilitate clinical diagnosis and personalized disease-risk profiling.
Journal ArticleDOI

Decoding ALS: from genes to mechanism

TL;DR: Extraordinary progress in understanding the biology of ALS provides new reasons for optimism that meaningful therapies will be identified, and emerging themes include dysfunction in RNA metabolism and protein homeostasis, with specific defects in nucleocytoplasmic trafficking.
Journal ArticleDOI

Converging mechanisms in ALS and FTD: disrupted RNA and protein homeostasis.

TL;DR: It is presented the case here that these two processes are intimately linked, with disease-initiated perturbation of either leading to further deviation of both protein and RNA homeostasis through a feedforward loop including cell-to-cell prion-like spread that may represent the mechanism for relentless disease progression.
Journal ArticleDOI

State of play in amyotrophic lateral sclerosis genetics.

TL;DR: Current literature of the major genes underlying ALS, SOD1, TARDBP, FUS, OPTN, VCP, UBQLN2, C9ORF72 and PFN1 are summarized and how each new genetic discovery is broadening the phenotype associated with the clinical entity the authors know as ALS is outlined.

PLINK: A Tool Set for Whole-Genome Association and Population-Based Linkage Analyses

TL;DR: This work introduces PLINK, an open-source C/C++ WGAS tool set, and describes the five main domains of function: data management, summary statistics, population stratification, association analysis, and identity-by-descent estimation, which focuses on the estimation and use of identity- by-state and identity/descent information in the context of population-based whole-genome studies.

Haploview: analysis and visualization of LD and haplotype maps

TL;DR: Haploview is a software package that provides computation of linkage disequilibrium statistics and population haplotype patterns from primary genotype data in a visually appealing and interactive interface.
Journal ArticleDOI

Mutations in Cu/Zn superoxide dismutase gene are associated with familial amyotrophic lateral sclerosis

TL;DR: Tight genetic linkage between FALS and a gene that encodes a cytosolic, Cu/Zn-binding superoxide dismutase (SOD1), a homodimeric metalloenzyme that catalyzes the dismutation of the toxic superoxide anion O–2 to O2 and H2O2 is reported.

Merlin--rapid analysis of dense genetic maps using sparse gene flow trees.

TL;DR: The multipoint engine for rapid likelihood inference (Merlin) is a computer program that uses sparse inheritance trees for pedigree analysis; it performs rapid haplotyping, genotype error detection and affected pair linkage analyses and can handle more markers than other pedigree analysis packages.
