title: Clinical genetic study of 144 patients with nonsyndromic hearing loss.
abstract: Hearing loss constitutes an important category of congenital defects that can be isolated or part of the phenotypic spectrum of several syndromes. A clinical genetic study was performed on a sample of 144 patients with nonsyndromic hearing loss, establishing the sex distribution, type, degree, symmetry, laterality, progression, etiology, and, when possible, inheritance pattern.
