Genes affected

WWP1 (HGNC:17004): (WW domain containing E3 ubiquitin protein ligase 1) WW domain-containing proteins are found in all eukaryotes and play an important role in the regulation of a wide variety of cellular functions such as protein degradation, transcription, and RNA splicing. This gene encodes a protein which contains 4 tandem WW domains and a HECT (homologous to the E6-associated protein carboxyl terminus) domain. The encoded protein belongs to a family of NEDD4-like proteins, which are E3 ubiquitin-ligase molecules and regulate key trafficking decisions, including targeting of proteins to proteosomes or lysosomes. Alternative splicing of this gene generates at least 6 transcript variants; however, the full length nature of these transcripts has not been defined. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.1714T>A (p.S572T) alteration is located in exon 16 (coding exon 14) of the WWP1 gene. This alteration results from a T to A substitution at nucleotide position 1714, causing the serine (S) at amino acid position 572 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
