Deleting the Tyr 3′ element in mice does not alter the pattern Tyr gene expression. (a) Diagram of the Tyr locus illustrating the position of the sgRNAs used for deletion of the Tyr 3′ boundary. (b) Alignment of the deletion alleles in two mouse lines. Line TYRINS3#16 carries a 2892 bp deletion; line TYRINS3#26 carries a smaller deletion (2316 bp) that spares the sequence targeted by sgRNA 3′5. (c) The coat color of wild-type (left) and TYRINS3 homozygous (right) animals is indistinguishable. (d) Skin and (e) eye relative melanin content of TYRINS3#16, TYRINS3#26 homozygous and wild-type mice. Whole mounts of retinae from wild-type (f) and TYRINS3 homozygous (g) animals.
