Genes affected

WBP4 (HGNC:12739): (WW domain binding protein 4) This gene encodes WW domain-containing binding protein 4. The WW domain represents a small and compact globular structure that interacts with proline-rich ligands. This encoded protein is a general spliceosomal protein that may play a role in cross-intron bridging of U1 and U2 snRNPs in the spliceosomal complex A. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.191A>T (p.E64V) alteration is located in exon 4 (coding exon 4) of the WBP4 gene. This alteration results from a A to T substitution at nucleotide position 191, causing the glutamic acid (E) at amino acid position 64 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
