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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 19, 2022The c.922A>G (p.I308V) 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 922, causing the isoleucine (I) at amino acid position 308 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
