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.

Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpJul 28, 2023This sequence change creates a premature translational stop signal (p.Pro78Glnfs*3) in the DDX41 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in DDX41 are known to be pathogenic (PMID: 26712909, 27133828). This variant is not present in population databases (gnomAD no frequency). This premature translational stop signal has been observed in individual(s) with hematologic malignancies (PMID: 35419889). ClinVar contains an entry for this variant (Variation ID: 434917). For these reasons, this variant has been classified as Pathogenic. -
