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 GeneticsJun 04, 2024The c.7A>G (p.T3A) alteration is located in exon 1 (coding exon 1) of the WDR20 gene. This alteration results from a A to G substitution at nucleotide position 7, causing the threonine (T) at amino acid position 3 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
