A bioinformatic analysis using UCSC Genome Browser on Human (GRCh38/hg38) searching for Transcription factors and SNPs in the CHI3L1 region studied showed predicted binding sites (Table S1) for 4 Zinc finger proteins (ZNF263, ZNF574, ZNF701, and ZNF531 or ZFP14) in the CpG1 site of CHI3L1, remarking ZNF263 that has been associated with regulation in asthma [74,75]). Here, ZNF574 is linked to asthma.
