Genes affected

DCAF6 (HGNC:30002): (DDB1 and CUL4 associated factor 6) The protein encoded by this gene is a ligand-dependent coactivator of nuclear receptors, including nuclear receptor subfamily 3 group C member 1 (NR3C1), glucocorticoid receptor (GR), and androgen receptor (AR). The encoded protein and DNA damage binding protein 2 (DDB2) may act as tumor promoters and tumor suppressors, respectively, by regulating the level of androgen receptor in prostate tissues. In addition, this protein can act with glucocorticoid receptor to promote human papillomavirus gene expression. [provided by RefSeq, Mar 2017]

The c.258G>C (p.L86F) alteration is located in exon 4 (coding exon 4) of the DCAF6 gene. This alteration results from a G to C substitution at nucleotide position 258, causing the leucine (L) at amino acid position 86 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
