A P2RX2 exon-2 complex indel disrupts splicing and reduces P2X2 output: implications for DFNA41 and variable expressivity
P2RX2 encodes the ATP-gated P2X2 receptor associated with autosomal dominant non-syndromic hearing loss 41 (DFNA41). DFNA41 is characterized by progressive sensorineural hearing loss and an increased susceptibility to acoustic trauma. However, the specific phenotypic consequences of truncating or splice-altering...
