Genes affected

WDR20 (HGNC:19667): (WD repeat domain 20) This gene encodes a WD repeat-containing protein that functions to preserve and regulate the activity of the USP12-UAF1 deubiquitinating enzyme complex. Multiple alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Jun 2011]

The c.1324G>C (p.A442P) alteration is located in exon 4 (coding exon 4) of the WDR20 gene. This alteration results from a G to C substitution at nucleotide position 1324, causing the alanine (A) at amino acid position 442 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
