Genes affected

DDX60 (HGNC:25942): (DExD/H-box helicase 60) DEAD box proteins, characterized by the conserved motif Asp-Glu-Ala-Asp (DEAD), are putative RNA helicases which are implicated in a number of cellular procsses involving RNA binding and alteration of RNA secondary structure. This gene encodes a DEXD/H box RNA helicase that functions as an antiviral factor and promotes RIG-I-like receptor-mediated signaling. [provided by RefSeq, Apr 2017]

The c.3650A>G (p.N1217S) alteration is located in exon 27 (coding exon 26) of the DDX60 gene. This alteration results from a A to G substitution at nucleotide position 3650, causing the asparagine (N) at amino acid position 1217 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
