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]

DDX43 links:

OOEP (HGNC:21382): (oocyte expressed protein) Predicted to enable RNA binding activity. Predicted to be involved in several processes, including cytoskeleton organization; positive regulation of double-strand break repair via homologous recombination; and positive regulation of meiotic nuclear division. Predicted to act upstream of or within several processes, including embryo implantation; in utero embryonic development; and protein phosphorylation. Located in cytoplasm and nucleus. Part of subcortical maternal complex. [provided by Alliance of Genome Resources, Apr 2022]

The c.182T>A (p.V61E) alteration is located in exon 1 (coding exon 1) of the DDX43 gene. This alteration results from a T to A substitution at nucleotide position 182, causing the valine (V) at amino acid position 61 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
