Genes affected

DHX38 (HGNC:17211): (DEAH-box helicase 38) 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 family are believed to be involved in embryogenesis, spermatogenesis, and cellular growth and division. The protein encoded by this gene is a member of the DEAD/H box family of splicing factors. This protein resembles yeast Prp16 more closely than other DEAD/H family members. It is an ATPase and essential for the catalytic step II in pre-mRNA splicing process. [provided by RefSeq, Jul 2008]

In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant¬† is likely to be tolerated. ClinVar contains an entry for this variant (Variation ID: 1419805). This variant has not been reported in the literature in individuals affected with DHX38-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.006%). This sequence change replaces alanine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 32 of the DHX38 protein (p.Ala32Val). -
