Title: Personalized smoking cessation: interactions between nicotine dose, dependence and quit-success genotype score.
ZNF295 may be involved in the bi-directional control of gene expression in concert with ZFP161

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
