Genetic Studies of Tone Deafness
NCT00006076 · View on ClinicalTrials.gov ↗
Study Summary
This study will examine the hereditary basis of tone deafness by identifying regions of the human genome linked to this condition. Both exceptionally good pitch recognition (perfect pitch) and exceptionally poor pitch recognition (tone deafness) run in families. A better understanding of what causes tone deafness may provide new insights into auditory (hearing) function. Individuals with two or more family members 15 years of age or older who are tone deaf or have trouble recognizing different melodies may be eligible for this study. Candidates will be screened with a short listening test for pitch and a short written test. Those identified with poor pitch recognition will fill out a brief questionnaire about their family tree and family members (without identifying names) who have trouble recognizing melodies or tones. Individuals with poor pitch recognition will be asked to help contact family members who may be interested in participating. Members of families with two or more first-degree relatives (parents, grandparents, siblings) who are tone deaf may enroll in the study. They will provide a blood sample (about 2 tablespoons) for genetic studies and may take a 20-minute hearing test using headphones.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00006076
The ClinicalTrials.gov registry entry for NCT00006076 describes a study currently listed as completed. It is categorized as an unspecified phase, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 968 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is National Institute on Deafness and Other Communication Disorders (NIDCD), which has 7 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 2 conditions, with Healthy appearing as the primary indexed condition, and to 0 interventions. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT00006076 reports 1 study location spanning 1 distinct geographic area — top geographies include Maryland. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
