MYH14 and bile duct papillary neoplasm: Actually, only one case has been reported with IPN and hearing loss (Choi et al., 2011), and two articles have been published about hearing loss with the same pathogenic variants (Chen et al., 1995; Mirghomizadeh et al., 2002).We can wonder whether a founder effect exists, or if a pathogenic variant in a HL gene close to MYH14 exists.
