Abstract

It has been hypothesized that dysfunction of the solute carrier family 1, member1 gene (SLC1A1), which encodes the glutamate aspartate transporter, may play a role in normal tension glaucoma. In this study we investigate whether SLC1A1 is associated with normal tension glaucoma in Japanese patients. A total of 292 Japanese patients with normal tension glaucoma and 500 healthy control subjects were recruited. We genotyped 12 single-nucleotide polymorphisms in SLC1A1. We also performed an imputation analysis to evaluate the potential association of un-genotyped SLC1A1 single-nucleotide polymorphisms, and 165 single-nucleotide polymorphisms were imputed. We observed an increased frequency of the G allele of rs10739062 in patients compared to controls (p = 0.043, OR = 1.25). The rs10739062 polymorphism exhibited a dominant effect: individuals with genotype GG and GC showed a 1.91-fold increase in risk compared to genotype CC (p = 0.0082). However, the statistical significance disappeared after Bonferroni correction for multiple testing (pc > 0.05). We did not find any significant association between any of the remaining 176 single-nucleotide polymorphisms and disease risk. Our study showed a lack of association between SLC1A1 variants and normal tension glaucoma in Japanese patients, suggesting that the SLC1A1 gene does not play a critical role in the development of the disorder in this patient population. However, further genetic studies with larger sample sizes are needed to clarify whether SLC1A1 may make some contribution that affects the risk of developing normal tension glaucoma.

Attention Score in Context

Attention Score in Context

This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 18 February 2016.
All research outputs
#20,308,732
of 22,849,304 outputs
Outputs from Ophthalmic Genetics
#344
of 529 outputs
Outputs of similar age
#332,538
of 395,880 outputs
Outputs of similar age from Ophthalmic Genetics
#20
of 41 outputs
Altmetric has tracked 22,849,304 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 529 research outputs from this source. They receive a mean Attention Score of 2.2. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 395,880 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 41 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
