Genes affected

NEDD4 (HGNC:7727): (NEDD4 E3 ubiquitin protein ligase) This gene is the founding member of the NEDD4 family of HECT ubiquitin ligases that function in the ubiquitin proteasome system of protein degradation. The encoded protein contains an N-terminal calcium and phospholipid binding C2 domain followed by multiple tryptophan-rich WW domains and, a C-terminal HECT ubiquitin ligase catalytic domain. It plays critical role in the regulation of a number of membrane receptors, endocytic machinery components and the tumor suppressor PTEN. [provided by RefSeq, Jul 2016]

The c.3225C>G (p.N1075K) alteration is located in exon 16 (coding exon 16) of the NEDD4 gene. This alteration results from a C to G substitution at nucleotide position 3225, causing the asparagine (N) at amino acid position 1075 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
