Genes affected

DDX42 (HGNC:18676): (DEAD-box helicase 42) This gene encodes a member of the Asp-Glu-Ala-Asp (DEAD) box protein family. Members of this protein family are putative RNA helicases, and 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. Members of this family are believed to be involved in embryogenesis, spermatogenesis, and cellular growth and division. Two transcript variants encoding the same protein have been identified for this gene. [provided by RefSeq, Jul 2008]

The c.1186A>G (p.T396A) alteration is located in exon 12 (coding exon 10) of the DDX42 gene. This alteration results from a A to G substitution at nucleotide position 1186, causing the threonine (T) at amino acid position 396 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
