Genes affected

DHX34 (HGNC:16719): (DExH-box helicase 34) DEAD box proteins, characterized by the conserved motif Asp-Glu-Ala-Asp (DEAD), are putative RNA helicases. They are implicated in a number of cellular processes involving alteration of RNA secondary structure such as translation initiation, nuclear and mitochondrial splicing, and ribosome and spliceosome assembly. Based on their distribution patterns, some members of this DEAD box protein family are believed to be involved in embryogenesis, spermatogenesis, and cellular growth and division. This gene encodes a member of this family. It is mapped to the glioma 19q tumor suppressor region and is a tumor suppressor candidate gene. [provided by RefSeq, Jul 2008]

Ambry Genetics

Dec 09, 2023

The c.106C>T (p.R36C) alteration is located in exon 2 (coding exon 1) of the DHX34 gene. This alteration results from a C to T substitution at nucleotide position 106, causing the arginine (R) at amino acid position 36 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
