This genomic region is located approximately 25 kb downstream of the frizzled class receptor 1 (FZD1) gene. It was predicted to be a heart enhancer based on a classifier that assesses the presence and/or absence of various features implicated in heart development, including transcription factor binding sites. It was validated as a functional heart enhancer in a zebrafish in vivo reporter assay. [provided by RefSeq, Jun 2016]
