Genes affected

DBP (HGNC:2697): (D-box binding PAR bZIP transcription factor) The protein encoded by this gene is a member of the PAR bZIP transcription factor family and binds to specific sequences in the promoters of several genes, such as albumin, CYP2A4, and CYP2A5. The encoded protein can bind DNA as a homo- or heterodimer and is involved in the regulation of some circadian rhythm genes. [provided by RefSeq, Jul 2014]

The c.446C>T (p.A149V) alteration is located in exon 2 (coding exon 2) of the DBP gene. This alteration results from a C to T substitution at nucleotide position 446, causing the alanine (A) at amino acid position 149 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
