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 GeneticsSep 01, 2021The c.1084G>A (p.D362N) alteration is located in exon 4 (coding exon 4) of the WDR20 gene. This alteration results from a G to A substitution at nucleotide position 1084, causing the aspartic acid (D) at amino acid position 362 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
