Description : Autosomal dominant deafness-41 (DFNA41) is characterized by onset of progressive sensorineural
hearing loss usually in the second decade. The hearing loss is severe and ultimately
affects all frequencies. Exposure to noise exacerbates the hearing loss, particularly
at high frequencies (summary by Yan et al., 2013).;
Inheritance : Autosomal dominant;
Molecular basis : Caused by mutation in the purinergic receptor P2X, ligand-gated ion channel, 2 gene
(P2RX2, 600844.0001);
