Genes affected
DDX43 (HGNC:18677): (DEAD-box helicase 43) The protein encoded by this gene is an ATP-dependent RNA helicase in the DEAD-box family and displays tumor-specific expression. [provided by RefSeq, Jul 2008]
CGAS (HGNC:21367): (cyclic GMP-AMP synthase) Enables several functions, including 2',3'-cyclic GMP-AMP synthase activity; chromatin binding activity; and phosphatidylinositol-4,5-bisphosphate binding activity. Involved in several processes, including cellular response to exogenous dsRNA; positive regulation of intracellular signal transduction; and regulation of defense response. Located in several cellular components, including cytosol; nucleus; and site of double-strand break. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 31, 2023The c.1575T>G (p.D525E) alteration is located in exon 13 (coding exon 13) of the DDX43 gene. This alteration results from a T to G substitution at nucleotide position 1575, causing the aspartic acid (D) at amino acid position 525 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
