Genes affected

WWP2 (HGNC:16804): (WW domain containing E3 ubiquitin protein ligase 2) This gene encodes a member of the Nedd4 family of E3 ligases, which play an important role in protein ubiquitination. The encoded protein contains four WW domains and may play a role in multiple processes including chondrogenesis and the regulation of oncogenic signaling pathways via interactions with Smad proteins and the tumor suppressor PTEN. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene, and a pseudogene of this gene is located on the long arm of chromosome 10.

The c.134C>T (p.A45V) alteration is located in exon 4 (coding exon 2) of the WWP2 gene. This alteration results from a C to T substitution at nucleotide position 134, causing the alanine (A) at amino acid position 45 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
