Genes affected

DHX9 (HGNC:2750): (DExH-box helicase 9) This gene encodes a member of the DEAH-containing family of RNA helicases. The encoded protein is an enzyme that catalyzes the ATP-dependent unwinding of double-stranded RNA and DNA-RNA complexes. This protein localizes to both the nucleus and the cytoplasm and functions as a transcriptional regulator. This protein may also be involved in the expression and nuclear export of retroviral RNAs. Alternate splicing results in multiple transcript variants. Pseudogenes of this gene are found on chromosomes 11 and 13.[provided by RefSeq, Feb 2010]

The c.824A>G (p.K275R) alteration is located in exon 9 (coding exon 8) of the DHX9 gene. This alteration results from a A to G substitution at nucleotide position 824, causing the lysine (K) at amino acid position 275 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
