Genes affected

DEDD2 (HGNC:24450): (death effector domain containing 2) This gene encodes a nuclear-localized protein containing a death effector domain (DED). The encoded protein may regulate the trafficking of caspases and other proteins into the nucleus during death receptor-induced apoptosis. Alternative splicing results in multiple transcript variants.

Collection Method: clinical testing

The c.662G>A (p.R221Q) alteration is located in exon 5 (coding exon 4) of the DEDD2 gene. This alteration results from a G to A substitution at nucleotide position 662, causing the arginine (R) at amino acid position 221 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
