Genome-wide association study identifies 19p13.3 (UNC13A) and 9p21.2 as susceptibility loci for sporadic amyotrophic lateral sclerosis
Leonard van den Berg, Roel Ophoff and colleagues present a genome-wide association study of sporadic amyotrophic lateral sclerosis. The work uncovers associated SNPs at 9p21.2 and an associated locus at 19p13.3 mapping to the UNC13A gene. We conducted a genome-wide association study among 2,323 indi...

Summary: | Leonard van den Berg, Roel Ophoff and colleagues present a genome-wide association study of sporadic amyotrophic lateral sclerosis. The work uncovers associated SNPs at 9p21.2 and an associated locus at 19p13.3 mapping to the
UNC13A
gene.
We conducted a genome-wide association study among 2,323 individuals with sporadic amyotrophic lateral sclerosis (ALS) and 9,013 control subjects and evaluated all SNPs with
P
< 1.0 × 10
−4
in a second, independent cohort of 2,532 affected individuals and 5,940 controls. Analysis of the genome-wide data revealed genome-wide significance for one SNP, rs12608932, with
P
= 1.30 × 10
−9
. This SNP showed robust replication in the second cohort (
P
= 1.86 × 10
−6
), and a combined analysis over the two stages yielded
P
= 2.53 × 10
−14
. The rs12608932 SNP is located at 19p13.3 and maps to a haplotype block within the boundaries of
UNC13A
, which regulates the release of neurotransmitters such as glutamate at neuromuscular synapses. Follow-up of additional SNPs showed genome-wide significance for two further SNPs (rs2814707, with
P
= 7.45 × 10
−9
, and rs3849942, with
P
= 1.01 × 10
−8
) in the combined analysis of both stages. These SNPs are located at chromosome 9p21.2, in a linkage region for familial ALS with frontotemporal dementia found previously in several large pedigrees. |
