Genes affected

COMMD8 (HGNC:26036): (COMM domain containing 8) The protein encoded by this gene binds coiled-coil domain-containing protein 22 (CCDC22), and this complex can regulate the turnover of I-kappa-B and the activation of NF-kappa-B. [provided by RefSeq, Jul 2016]

The c.89G>A (p.G30D) alteration is located in exon 2 (coding exon 2) of the COMMD8 gene. This alteration results from a G to A substitution at nucleotide position 89, causing the glycine (G) at amino acid position 30 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
