Genes affected

DHX36 (HGNC:14410): (DEAH-box helicase 36) This gene is a member of the DEAH-box family of RNA-dependent NTPases which are named after the conserved amino acid sequence Asp-Glu-Ala-His in motif II. The protein encoded by this gene has been shown to enhance the deadenylation and decay of mRNAs with 3'-UTR AU-rich elements (ARE-mRNA). The protein has also been shown to resolve into single strands the highly stable tetramolecular DNA configuration (G4) that can form spontaneously in guanine-rich regions of DNA. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Jul 2008]

The c.2050G>C (p.E684Q) alteration is located in exon 18 (coding exon 18) of the DHX36 gene. This alteration results from a G to C substitution at nucleotide position 2050, causing the glutamic acid (E) at amino acid position 684 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
