Genes affected

DDX41 (HGNC:18674): (DEAD-box helicase 41) 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 the DEAD box protein 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 box protein family and interacts with several spliceosomal proteins. In addition, the encoded protein may recognize the bacterial second messengers cyclic di-GMP and cyclic di-AMP, resulting in the induction of genes involved in the innate immune response.

The DDX41 c.138+5G>T intronic change results from a G to T substitution at the +5 position of intron 2 of the DDX41 gene. Algorithms that predict the impact of sequence changes on splicing indicate that this change may result in loss of the native donor, but internal RNA data demonstrates normal splicing. This variant has a maximum subpopulation frequency of 0.026% in gnomAD v2.1.1 (https://gnomad.broadinstitute.org/). This variant has been reported in individuals with hematologic malignancies (PMID: 35671390, 37199125). In summary, the evidence currently available is insufficient to determine the clinical significance of this variant. It has therefore been classified as of uncertain significance. -

This sequence change falls in intron 2 of the DDX41 gene. It does not directly change the encoded amino acid sequence of the DDX41 protein. It affects a nucleotide within the consensus splice site. This variant is present in population databases (rs187714514, gnomAD 0.03%), and has an allele count higher than expected for a pathogenic variant. This variant has been observed in individual(s) with DDX41-related conditions (PMID: 35671390, 37199125). ClinVar contains an entry for this variant (Variation ID: 434923). Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. 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. -

Collection Method:clinical testing

The c.138+5G>T intronic variant results from a G to T substitution 5 nucleotides after coding exon 2 in the DDX41 gene. This variant was reported in individual(s) with features consistent with DDX41-related hematologic malignancy conditions (Li P et al. Blood, 2022 Aug;140:716-755; Badar T et al. Haematologica, 2023 Nov;108:3033-3043). This nucleotide position is highly conserved in available vertebrate species. In silico splice site analysis predicts that this alteration may weaken the native splice donor site. Based on the available evidence, the clinical significance of this variant remains unclear. -
