* A 14-year study analyzed over 700 patients with syndromic deafness (SD) in Tunisia, using advanced genetic sequencing techniques to identify various genetic conditions, including Usher syndrome and H syndrome.
* The research highlights challenges in distinguishing between non-syndromic and syndromic HI and reveals that nearly 50% of Tunisian SD cases relate to rare inherited metabolic disorders, providing valuable insights for improving molecular diagnoses in Tunisia and North Africa.
