Analytical Validity: Help
Alterations in the stereocilin (STRC) gene are the most common genetic etiology in patients with mild to moderate hearing loss, accounting for roughly 30% of patients in this group, and 16% among all patients with hearing loss. Most variants were large copy number variants (CNVs).
