Genes affected

DCAF8 (HGNC:24891): (DDB1 and CUL4 associated factor 8) This gene encodes a WD repeat-containing protein that interacts with the Cul4-Ddb1 E3 ligase macromolecular complex. Multiple alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Jul 2009]

Variant summary: WDR42A c.1684C>T (p.Arg562X) results in a premature termination codon in the last exon, predicted to cause a truncation of the encoded protein and not expected to result in nonsense mediated decay . No downstream pathogenic variants have been observed. The variant was absent in 281070 control chromosomes. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. To our knowledge, no occurrence of c.1684C>T in individuals affected with Giant Axonal Neuropathy 2 and no experimental evidence demonstrating its impact on protein function have been reported. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014. Based on the evidence outlined above, the variant was classified as uncertain significance. -
