Hair coloration ranges all through a big spectrum of hues, from flaxen blond to coal black. Many genes aside from MC1R play a job in determining shades of hair colour by controlling ranges of eumelanin and pheomelanin. Some of these genes, along with ASIP , DTNBP1 , GPR143 , HPS3 , KITLG , MLPH , MYO5A , MYO7A , OCA2 , SLC45A2 , SLC24A5 , TYRP1 , TYR , ERCC6 , GNAS , HERC2 , IRF4 , OBSCN , SLC24A4 , TPCN2 , and MITF , are concerned within the production of melanin in hair. A couple of of those genes are related to gene transcription (which is step one in protein manufacturing), DNA restore, the transport of drugs (corresponding to calcium) all through cell membranes, or the construction of hair follicles. A number of of these genes contribute to eye and pores and skin shade, but the precise function they play in determining hair coloration is unknown.
