In this project, Professor Patricia Perez-Carpena (University of Granada, Spain) aims to develop a new method to improve diagnosis of hearing loss in children. Project start date: April 2026 Project end date: March 2027 About the project ‘Sensorineural hearing loss’ is caused by damage to the sound-sensing hair cells in the inner ear, or to the hearing nerve, which carries information about sound to the brain....

✦ Clinical Takeaway ✦

No actionable change — this is an early-stage diagnostic development project with no published results yet.

✦ Why It Matters ✦

A more sensitive genetic diagnostic tool could reduce the proportion of childhood sensorineural hearing loss cases that go unexplained, enabling earlier targeted intervention and genetic counselling.

✦ Key Points ✦
  1. 01RNID is funding Prof. Patricia Perez-Carpena (University of Granada) to develop a new genetic diagnostic method for childhood hearing loss.
  2. 02The target condition is childhood sensorineural hearing loss (inner-ear or hearing-nerve damage present from birth or early life).
  3. 03The focus is on 'hidden' genetic causes not detected by current methods.
  4. 04Project runs April 2026–March 2027; no results available yet.
  5. 05Success could improve diagnostic yield and inform genetic counselling for affected families.
✦ Claims & Evidence ✦

Current diagnostic methods fail to identify the genetic cause in a significant proportion of childhood sensorineural hearing loss cases.
