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.1342A>G (p.S448G) alteration is located in exon 4 (coding exon 4) of the WDR20 gene. This alteration results from a A to G substitution at nucleotide position 1342, causing the serine (S) at amino acid position 448 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
