Genes affected

DCAF12L1 (HGNC:29395): (DDB1 and CUL4 associated factor 12 like 1) This gene encodes a member of the WD repeat protein family. WD repeats are minimally conserved regions of approximately 40 amino acids typically bracketed by gly-his and trp-asp (GH-WD), which may facilitate formation of heterotrimeric or multiprotein complexes. Members of this family are involved in a variety of cellular processes, including cell cycle progression, signal transduction, apoptosis, and gene regulation. [provided by RefSeq, Jul 2008]

The c.55G>A (p.D19N) alteration is located in exon 1 (coding exon 1) of the DCAF12L1 gene. This alteration results from a G to A substitution at nucleotide position 55, causing the aspartic acid (D) at amino acid position 19 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
