Single nucleotide polymorphism analysis in interstitial cystitis/painful bladder syndrome

Area of Science:

• Genetics
• Urology
• Biomarkers

Background:

• Interstitial Cystitis (IC) is a chronic condition characterized by pelvic pain and urinary urgency, lacking objective diagnostic markers.
• The etiology and pathogenesis of IC remain poorly understood, complicating diagnosis and management.
• Identifying reliable biomarkers is crucial for advancing IC diagnosis and treatment.

Purpose of the Study:

• To investigate the association between 20 selected single nucleotide polymorphisms (SNPs) and Interstitial Cystitis (IC).
• To explore the correlation of these SNPs with the severity of chronic pain experienced by IC patients.
• To identify potential genetic markers for IC diagnosis and pain assessment.

Main Methods:

• A case-control study involving 34 female IC patients and 23 controls.
• Genotyping of 20 selected SNPs using real-time PCR (q-PCR).
• IC patients were categorized by pain severity for comparative analysis.

Main Results:

• The polymorphic allele of SNP rs11127292 was significantly more frequent in IC patients compared to controls (p=0.01).
• SNP rs6311's polymorphic allele was more prevalent in patients with severe pain (p=0.03).
• The wild-type allele of SNP rs1799971 was more frequent in patients with mild to moderate pain (p=0.04).

Conclusions:

• Specific SNPs show potential as biomarkers for Interstitial Cystitis (IC).
• Certain SNPs may also serve as indicators for pain severity in IC patients.
• These novel associations between SNPs and IC warrant further investigation.
