chr20_54107677_C_A
Regulatory target CYP24A1 is taken from curated literature, not from distance. For a non-coding regulatory variant the nearest gene by distance is frequently not the regulated gene.
Receptor variant-effect scores
Strongest effect: FXR LoF at normalized -0.844. Impact is high, in the upper range toward the 99th percentile.
ft_head_delta_norm = center bin sum of ALT minus REF on the receptor CHIP_TF head, normalized to the peak population 99th percentile and clipped to [−1, 1]. AhR is reported as exploratory, single replicate.

Every possible base substitution at chr20:54107677, each scored independently. The gnomAD column shows which substitution is actually seen in the population versus in silico only. Region confidence is the same for every substitution at this position, so it is shown once in the section below.
Region confidence
In receptor peaks: PXR
Multi receptor overlap: PXR
