Genome-wide Association Studies-GWAS01:11

Genome-wide Association Studies-GWAS

Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...

Anatomy of the Genitourinary System II: Bladder and Urethra

The lower urinary system consists of the urinary bladder and urethra, which are essential in storing and expelling urine from the body. Together with the internal and external sphincters, these structures work together to regulate urination effectively.Anatomy of the BladderThe urinary bladder is a muscular, stretchable organ behind the pubic bone and in front of the rectum. In females, the bladder is positioned anterior to the vagina and inferior to the uterus, while in males, it is located...

Urologic Endoscopic Procedure: Cystoscopic Examination

Meaning of Cystoscopic Examination:Cystoscopy is an essential diagnostic tool in urology that is used to assess the structure and function of the genitourinary system. It provides a direct view of the urethra, bladder, and, in some cases, the ureteral openings. This procedure helps detect structural abnormalities, infections, cancers, and blockages in the urinary tract. There are two types of cystoscopy:Flexible cystoscopy is commonly performed in outpatient settings due to its less invasive...

Imaging Studies VI: Voiding Cystourethrography and Cystography

Voiding Cystourethrography (VCUG) and Cystography are specialized radiographic procedures used to examine the structure and function of the bladder and urethra.Voiding Cystourethrography (VCUG)A Voiding Cystourethrogram (VCUG) is a diagnostic imaging procedure that assesses the anatomy and function of the lower urinary tract. It focuses on the bladder, bladder neck, and urethra, helping detect abnormalities such as vesicoureteral reflux (VUR)—the backward or reverse flow of urine into the...

Area of Science:

  • Genetics
  • Urology
  • Developmental Biology

Background:

  • Bladder exstrophy-epispadias complex involves failed closure of the distal urinary tract.
  • Previous research suggests a multifactorial inheritance pattern, but specific factors remain unidentified.

Purpose of the Study:

  • To identify chromosomal regions associated with bladder exstrophy-epispadias complex.
  • To investigate potential genetic risk loci using linkage analysis.

Main Methods:

  • Genome-wide linkage scan performed on two pedigrees with classical bladder exstrophy.
  • Utilized parametric and nonparametric linkage analysis to search for risk loci.

Main Results:

  • Identified potential risk/modifying loci on chromosomes 2, 4, 7, 14, and 19.
  • Evidence for loci on specific chromosomal bands including 2p22.1-p21 and 7q21.3-q33.

Conclusions:

  • This study represents the first positional approach to identify candidate regions for bladder exstrophy-epispadias complex.
  • Results suggest the presence of susceptibility genes in the identified chromosomal regions.
  • Further studies are required to confirm these findings.
