Species-specific description: This phene includes references to studies involving genetically modified organisms (GMO). Hu et al. (2017): "generated 3 FGF5 knockout sheep via the 1-step clustered regularly interspaced short palindromic repeat (CRISPR)/Cas9 system. Sequencing analysis confirmed that mutations in the FGF5 gene existed in all germ lines of 3 founders: besides the intact sequence, 3 kinds of deletions in the FGF5 gene (including 5, 13, and 33 bp) were detected. The changes in the primary and senior structure of the FGF5 protein due to the 3 deletions in founders suggested that the FGF5 protein was dysfunctional. In addition, the expression level of intact FGF5 mRNA in heterozygous individuals decreased compared with the wild types (P < 0.01). Functionally, we discovered that wool length in founders was significantly longer than in wild types (P < 0.05)." Zhang et al. (2020): "generated five FGF5-knockout Dorper sheep by the CRISPR/Cas9 system. The expression level of FGF5 mRNA in knockout (KO) sheep decreased significantly, and all FGF5 proteins were dysfunctional. The KO sheep displayed a significant increase in fine-wool and active hair-follicle density."

Genetic engineering: Yes - variants have been created artificially, e.g. by genetic engineering or gene editing
Have human generated variants been created, e.g. through genetic engineering and gene editing
