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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 30, 2024The c.1770C>A (p.D590E) alteration is located in exon 14 (coding exon 12) of the DCAF8 gene. This alteration results from a C to A substitution at nucleotide position 1770, causing the aspartic acid (D) at amino acid position 590 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
