AI Article Synopsis
- Whole Exome Sequencing (WES) was utilized to identify genetic defects in Jordanian patients with inherited retinal dystrophies (IRDs), analyzing DNA from 55 families.
- The study found 35 potential disease-causing variants, including 6 novel and 29 previously known, in a significant portion of the probands (71%).
- This research represents the largest genetic analysis of IRDs in Jordan, demonstrating WES's effectiveness for diagnosing IRDs in large patient groups.
Article Abstract
Whole Exome Sequencing (WES) is a powerful approach for detecting sequence variations in the human genome. The aim of this study was to investigate the genetic defects in Jordanian patients with inherited retinal dystrophies (IRDs) using WES. WES was performed on proband patients' DNA samples from 55 Jordanian families. Sanger sequencing was used for validation and segregation analysis of the detected, potential disease-causing variants (DCVs). Thirty-five putatively causative variants (6 novel and 29 known) in 21 IRD-associated genes were identified in 71% of probands (39 of the 55 families). Three families showed phenotypes different from the typically reported clinical findings associated with the causative genes. To our knowledge, this is the largest genetic analysis of IRDs in the Jordanian population to date. Our study also confirms that WES is a powerful tool for the molecular diagnosis of IRDs in large patient cohorts.
