The KEGG pathway analysis of DEGs in flrt2-KO zebrafish eyes compared with WT found that they were enriched in the following pathways: Pantothenate and CoA biosynthesis, Pyrimidine metabolism, Fanconi anemia pathway, Drug metabolism-other enzymes, 2-Oxocarboxylic acid metabolism, linoleic acid metabolism and necroptosis. The gene discussed is FLRT2; the disease is Fanconi anemia.
