Genes affected

DDX53 (HGNC:20083): (DEAD-box helicase 53) This intronless gene encodes a protein which contains several domains found in members of the DEAD-box helicase protein family. Other members of this protein family participate in ATP-dependent RNA unwinding. [provided by RefSeq, Sep 2011]

The c.80G>A (p.S27N) alteration is located in exon 1 (coding exon 1) of the DDX53 gene. This alteration results from a G to A substitution at nucleotide position 80, causing the serine (S) at amino acid position 27 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
