| Abstract |
Endometriosis is a common gynaecological disease, associated with severe pelvic pain and reduced fertility; however, molecular mechanisms remain largely unknown. Genome-wide association studies (GWAS) are able to identify genetic loci, which can play significant role during endometriosis development. The study aimed at localisation of new genes and chromosomal loci, the nucleotide variants of which determine the level of susceptibility to endometriosis. Blood samples from 171 patients with endometriosis were used as material for studies. The patients were recruited to the study at the Department of Operative Gynaecology of the Institute of the Polish Mother's Memorial Hospital in Lodz. A control group (n=2934) came from the POPULOUS collection registered at Biobank Lab, Department of Molecular Biophysics, University of Lodz. DNA of the patients with endometriosis was compared with DNA of women free from that disease, the comparison being supported by GWAS. Genome-wide significant correlation was identified between one new, not previously described, single nucleotide polymorphism (SNP), rs10129516, localised on chromosome 14 in intergenic region between PARP1P2 and RHOJ genes (p=1.44×10(-10), OR=3.104, 95% CI=2.329-4.136) and endometriosis. We have also identified significant association with endometriosis of 18 SNPs localised on chromosome 6 in position range 31883957 - 32681631 (C2 and HLA-DRA genes region) with the lowest observed p value for rs644045 in C2 gene (p=2.04×10(-8), OR=1.955, 95% CI=1.541-2.480). Reported GWAS identified the novel loci associated with endometriosis in Polish women, not previously reported. The most interesting observation shown in our study are regions associated with susceptibility to endometriosis of loci located near C2, HLA-DRA and RHOJ genes. of that study did not correspond to previously published data about polymorphism in that regions and further evaluations are necessary in groups with higher numbers of patients to explain whether the above-mentioned genetic variant may be the risk factor for pathogenesis of endometriosis. |

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 08 September 2017.
All research outputs
#22,764,772
of 25,382,440 outputs
Outputs from European Journal of Obstetrics & Gynecology & Reproductive Biology
#3,321
of 3,869 outputs
Outputs of similar age
#284,752
of 324,453 outputs
Outputs of similar age from European Journal of Obstetrics & Gynecology & Reproductive Biology
#48
of 84 outputs
Altmetric has tracked 25,382,440 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 3,869 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.1. 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 324,453 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 84 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.
