Genes affected
DHX9 (HGNC:2750): (DExH-box helicase 9) This gene encodes a member of the DEAH-containing family of RNA helicases. The encoded protein is an enzyme that catalyzes the ATP-dependent unwinding of double-stranded RNA and DNA-RNA complexes. This protein localizes to both the nucleus and the cytoplasm and functions as a transcriptional regulator. This protein may also be involved in the expression and nuclear export of retroviral RNAs. Alternate splicing results in multiple transcript variants. Pseudogenes of this gene are found on chromosomes 11 and 13.[provided by RefSeq, Feb 2010]
DHX9 Gene-Disease associations (from GenCC):
  • intellectual developmental disorder, autosomal dominant 75

ACMG classification

Classification was made for transcript

Our verdict: Uncertain_significance. The variant received 1 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 2 curated pathogenic missense variants (we use a threshold of 10). The gene has 0 curated benign missense variants. Gene score misZ: 5.8433 (above the threshold of 3.09). Trascript score misZ: 7.2163 (above the threshold of 3.09). GenCC associations: The gene is linked to intellectual developmental disorder, autosomal dominant 75.
BP4
Computational evidence support a benign effect (MetaRNN=0.068705976).
