Mutations in Cu/Zn superoxide dismutase gene are associated with familial amyotrophic lateral sclerosis
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.
Gene dose of apolipoprotein E type 4 allele and the risk of Alzheimer's disease in late onset families.
APOE-epsilon 4 gene dose is a major risk factor for late onset AD and, in these families, homozygosity for APOE-epsilon 4 was virtually sufficient to cause AD by age 80.
Mutations in the FUS/TLS Gene on Chromosome 16 Cause Familial Amyotrophic Lateral Sclerosis
Neuronal cytoplasmic protein aggregation and defective RNA metabolism thus appear to be common pathogenic mechanisms involved in ALS and possibly in other neurodegenerative disorders.
Meta-analysis of 74,046 individuals identifies 11 new susceptibility loci for Alzheimer's disease
In addition to the APOE locus (encoding apolipoprotein E), 19 loci reached genome-wide significance (P < 5 × 10−8) in the combined stage 1 and stage 2 analysis, of which 11 are newly associated with Alzheimer's disease.
Segregation of a missense mutation in the amyloid precursor protein gene with familial Alzheimer's disease
It is demonstrated that in this kindred, which shows linkage to chromosome 21 markers, there is a point mutation in the APP gene that causes an amino-acid substitution close to the carboxy terminus of the β-amyloid peptide.
Cloning of a gene bearing missense mutations in early-onset familial Alzheimer's disease
A minimal cosegregating region containing the AD3 gene is defined, and at least 19 different transcripts encoded within this region corresponds to a novel gene whose product is predicted to contain multiple transmembrane domains and resembles an integral membrane protein.
Effects of Age, Sex, and Ethnicity on the Association Between Apolipoprotein E Genotype and Alzheimer Disease: A Meta-analysis
The APOE∈4 allele represents a major risk factor for AD in all ethnic groups studied, across all ages between 40 and 90 years, and in both men and women.

It is demonstrated that there was a highly significant association of apolipoprotein E type 4 allele (APOE-epsilon 4) and late-onset familial Alzheimer disease.
Mutations in UBQLN2 cause dominant X-linked juvenile and adult onset ALS and ALS/dementia
Findings link abnormalities in ubiquilin 2 to defects in the protein degradation pathway, abnormal protein aggregation and neurodegeneration, indicating a common pathogenic mechanism that can be exploited for therapeutic intervention.
Functional impact of global rare copy number variation in autism spectrum disorders
The genome-wide characteristics of rare (<1% frequency) copy number variation in ASD are analysed using dense genotyping arrays to reveal many new genetic and functional targets in ASD that may lead to final connected pathways.
