Genes affected
DHX29 (HGNC:15815): (DExH-box helicase 29) This gene encodes a member of the DEAH (Asp-Glu-Ala-His) subfamily of proteins, part of the DEAD (Asp-Glu-Ala-Asp) box family of RNA helicases. The encoded protein functions in translation initiation, and is specifically required for ribosomal scanning across stable mRNA secondary structures during initiation codon selection. This protein may also play a role in sensing virally derived cytosolic nucleic acids. Knockdown of this gene results in reduced protein translation and impaired proliferation of cancer cells.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Dec 27, 2023 | The c.2975G>A (p.R992Q) alteration is located in exon 19 (coding exon 19) of the DHX29 gene. This alteration results from a G to A substitution at nucleotide position 2975, causing the arginine (R) at amino acid position 992 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
