The CYB5R1 gene is located on the 1st chromosome, with its specific location being 1q32.1. The gene contains 9

exons An exon is any part of a gene that will form a part of the final mature RNA produced by that gene after introns have been removed by RNA splicing. The term ''exon'' refers to both the DNA sequence within a gene and to the corresponding sequenc ...
