Genes affected

DCAF12 (HGNC:19911): (DDB1 and CUL4 associated factor 12) This gene encodes a WD repeat-containing protein that interacts with the COP9 signalosome, a macromolecular complex that interacts with cullin-RING E3 ligases and regulates their activity by hydrolyzing cullin-Nedd8 conjugates.

The c.952C>T (p.H318Y) alteration is located in exon 7 (coding exon 7) of the DCAF12 gene. This alteration results from a C to T substitution at nucleotide position 952, causing the histidine (H) at amino acid position 318 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
