dbSNP rs376929047: DDX43:p.Phe78Val (chr6-73395137-T-G) – ACMG Classification: Likely_benign (-4 pts)

Variant summary

Our verdict is Likely benign. The variant received -4 ACMG points: 0P and 4B. BP4_Strong

The NM_018665.3(DDX43):c.232T>G(p.Phe78Val) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000539 in 1,613,224 control chromosomes in the GnomAD database, including 1 homozygotes. In-silico tool predicts a benign outcome for this variant. 15/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. F78S) has been classified as Uncertain significance.

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]
