Genes affected

WBP11 (HGNC:16461): (WW domain binding protein 11) This gene encodes a nuclear protein, which colocalizes with mRNA splicing factors and intermediate filament-containing perinuclear networks. This protein has 95% amino acid sequence identity to the mouse Wbp11 protein. It contains two proline-rich regions that bind to the WW domain of Npw38, a nuclear protein, and thus this protein is also called Npw38-binding protein NpwBP. The Npw38-NpwBP complex may function as a component of an mRNA factory in the nucleus. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in gene, where missense usually causes diseases (based on misZ statistic), WBP11. . Gene score misZ 2.9803 (greater than the threshold 3.09). Trascript score misZ 3.4119 (greater than threshold 3.09). GenCC has associacion of gene with vertebral, cardiac, tracheoesophageal, renal, and limb defects.
• BP4: Computational evidence support a benign effect (MetaRNN=0.2493316).

The c.1577C>T (p.A526V) alteration is located in exon 12 (coding exon 11) of the WBP11 gene. This alteration results from a C to T substitution at nucleotide position 1577, causing the alanine (A) at amino acid position 526 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
