ZBTB46

Chr 20

zinc finger and BTB domain containing 46

Also known as: BTBD4, BZEL, RINZF, ZNF340, dJ583P15.7, dJ583P15.8

ZBTB46 encodes a transcription repressor that regulates dendritic cell differentiation and immune tolerance to gut microbiota. The gene is highly constrained against loss-of-function variants (pLI 0.81, LOEUF 0.40), but no definitive Mendelian disease associations have been established in humans to date.
