Association the allelic variation and SNP rs12917707 genotyping with UMOD serum level among Iraqi patients infected with uropathogenic Escherichia coli

: The current study included 90 samples collected and divided into (45) Urinary tract infections of E. coli patients and (45) controls with different ages of both genders. Patient samples were collected from UTI patients admitted to ALYarmouk Teaching Hospital, AL-Karama Teaching Hospital and Al Kidney Teaching Hospital from November 2020 to March 2021. The current study measured Tamm Horsfall protein (THP) concentration in patients with Urinary tract infections and healthy groups. The study also included the Relationship of Umod rs12917707 genotype and Uromodulin level in patients and control using Nested T-ARMS PCR. Our study had two objectives: First, to address whether urinary uromodulin concentration is associated with urinary tract infection with E. coli in a community-based study, and second, to determine whether a single-nucleotide polymorphism (SNP) in the UMOD region, rs12917707, is associated with urinary uromodulin concentrations. After statistical analysis, the results showed that there could be an association between having mutant homozygous GG polymorphism in the UMOD gene and having UTI of E. coli. At the same time, the mutant homozygous TT represents a risk factor compared to other genotypes (ORs: 0.4, 95% CI (0.17 - 0.93 and ORs: 4.4, 95% CI (1.47-13.26) respectively. The results also showed a significant decrease at P≤0.01 in the patients group with Urinary tract infection (1.38 ± 0.03) Ng/ml compared with the control sample, which was (1.83 ± 0.04) Ng/ml.
