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]

Nov 30, 2022

The c.205G>A (p.V69M) alteration is located in exon 1 (coding exon 1) of the WDR20 gene. This alteration results from a G to A substitution at nucleotide position 205, causing the valine (V) at amino acid position 69 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
