Genes affected

TAS2R60 (HGNC:20639): (taste 2 receptor member 60) This gene encodes a member of the bitter taste receptor family which belong to the G protein-coupled receptor superfamily and are predominantly expressed in taste receptor cells of the tongue and palate epithelia. This intronless taste receptor gene encodes a seven-transmembrane receptor protein, functioning as a bitter taste receptor. This gene is clustered together with eight other taste receptor genes on chromosome 7. [provided by RefSeq, Jul 2017]

EPHA1-AS1 (HGNC:27799): (EPHA1 antisense RNA 1)

ENSG00000309456 (HGNC:):
