Trial summary

Two major limitations of existing audiometric newborn hearing screening programs are their inability to detect forms of deafness that are not expressed at birth and the low compliance with obtaining recommended audiologic confirmation and/or follow-up. Read more about this study

About this study

Official title: Utility of Genetic Testing in Detection of Late-Onset Hearing Loss

Two major limitations of existing audiometric newborn hearing screening programs are their inability to detect forms of deafness that are not expressed at birth and the low compliance with obtaining recommended audiologic confirmation and/or follow-up. Molecular genetic tests on blood spots from all newborns will identify those at risk for the most frequent causes of late-onset hearing loss and to add these infants to the group who should receive continued audiologic monitoring.

Read the detailed description

Two major limitations of existing audiometric newborn hearing screening programs are their inability to detect forms of deafness that are not expressed at birth and the low compliance with obtaining recommended audiologic confirmation and/or follow-up. Molecular genetic tests on blood spots from all newborns will identify those at risk for the most frequent causes of late-onset hearing loss and to add these infants to the group who should receive continued audiologic monitoring.

The specific aims of this project are to:

  • Demonstrate the utility of detecting four potentially important causes of delayed onset hearing loss by molecular tests at birth, which may be missed by current audiometric screening tests.
  • Document the frequency, clinical and genetic characteristics of hearing loss associated with each condition.

Dried blood spots (DBS) on filter paper will be obtained and be used for this project with parental informed consent from 6,000 newborn infants at approximately 25 hospitals. Pediatrix Screening, a subsidiary of Pediatrix Medical Group with long experience in high throughput neonatal testing, will perform genetic testing on the samples. The four genetic and environmental forms of deafness to be studied include:

  • Prenatal/congenital cytomegalovirus (CMV) infection -Detecting the presence of CMV viral DNA in dried blood spots.
  • Connexin Deafness - GJB2 and GJB6 mutations
  • Cx26 35delG, Cx26 235delC, Cx26 167delT, Cx26 M34T, and Cx30 large deletion.(Under sublicense with Athena Diagnostics, Inc: United States Patent Numbers: 5,998,147 and 6,485,908 and patents pending)
  • Pendred Syndrome - SLC26A mutations
  • L236P, 1001 +1G>A, T416P, E384G
  • Mitochondrial Mutations - T961C, T961G, G951A, 961 delT+C(n)Ins, G7444A, A7445G, A7445C.

Questions about this trial

What is this clinical trial studying?

An observational study of Hearing Loss and Late-Onset Hearing Loss, run by Pediatrix at 3 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 1 Mar 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Mar 2012.
