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]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.795C>A (p.F265L) alteration is located in exon 4 (coding exon 4) of the WDR20 gene. This alteration results from a C to A substitution at nucleotide position 795, causing the phenylalanine (F) at amino acid position 265 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
