Genes affected

WBP1 (HGNC:12737): (WW domain binding protein 1) The globular WW domain, named for the conserved tryptophan residues in the protein motif present in various structural and regulatory proteins, is known to play a role in the mediation of protein-protein interactions. This gene encodes a ligand of the WW domain of the Yes kinase-associated protein. Readthrough transcription of the neighboring upstream gene, which encodes INO80 complex subunit B, into this gene generates a non-coding transcript. [provided by RefSeq, Feb 2011]

INO80B-WBP1 (HGNC:):

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.21986178).

The c.103C>T (p.P35S) alteration is located in exon 2 (coding exon 2) of the WBP1 gene. This alteration results from a C to T substitution at nucleotide position 103, causing the proline (P) at amino acid position 35 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
