Genes affected

U2AF2 (HGNC:23156): (U2 small nuclear RNA auxiliary factor 2) U2 auxiliary factor (U2AF), comprised of a large and a small subunit, is a non-snRNP protein required for the binding of U2 snRNP to the pre-mRNA branch site. This gene encodes the U2AF large subunit which contains a sequence-specific RNA-binding region with 3 RNA recognition motifs and an Arg/Ser-rich domain necessary for splicing. The large subunit binds to the polypyrimidine tract of introns early during spliceosome assembly. Multiple transcript variants have been detected for this gene, but the full-length natures of only two have been determined to date. [provided by RefSeq, Jul 2008]

U2AF2 Gene-Disease associations (from GenCC):

• developmental delay, dysmorphic facies, and brain anomalies

  Inheritance: AD Classification: STRONG Submitted by: Ambry Genetics

ACMG classification

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 7 curated pathogenic missense variants (we use a threshold of 10). The gene has 0 curated benign missense variants. Gene score misZ: 4.7134 (above the threshold of 3.09). Trascript score misZ: 6.409 (above the threshold of 3.09). GenCC associations: The gene is linked to developmental delay, dysmorphic facies, and brain anomalies.
• BP4: Computational evidence support a benign effect (MetaRNN=0.17734024).
