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]

Ambry Genetics

Aug 13, 2021

The c.96G>C (p.W32C) alteration is located in exon 1 (coding exon 1) of the DDX53 gene. This alteration results from a G to C substitution at nucleotide position 96, causing the tryptophan (W) at amino acid position 32 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
