Deafness, Autosomal Recessive 74, also known as dfnb74, is related to age-related hearing loss and nonsyndromic hearing loss. An important gene associated with Deafness, Autosomal Recessive 74 is MSRB3 (Methionine Sulfoxide Reductase B3), and among its related pathways/superpathways are PPAR signaling pathway and Overlap between signal transduction pathways contributing to LMNA laminopathies. Affiliated tissues include brain, and related phenotypes are hearing impairment and rod-cone dystrophy
