Genes affected

SMURF1 (HGNC:16807): (SMAD specific E3 ubiquitin protein ligase 1) This gene encodes a ubiquitin ligase that is specific for receptor-regulated SMAD proteins in the bone morphogenetic protein (BMP) pathway. This protein plays a key roll in the regulation of cell motility, cell signalling, and cell polarity. Alternative splicing results in multiple transcript variants encoding different isoforms.[provided by RefSeq, Dec 2010]

SMURF1 links:

TRRAP (HGNC:12347): (transformation/transcription domain associated protein) This gene encodes a large multidomain protein of the phosphoinositide 3-kinase-related kinases (PIKK) family. The encoded protein is a common component of many histone acetyltransferase (HAT) complexes and plays a role in transcription and DNA repair by recruiting HAT complexes to chromatin. Deregulation of this gene may play a role in several types of cancer including glioblastoma multiforme. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Sep 2011]

The c.1519A>T (p.N507Y) alteration is located in exon 14 (coding exon 14) of the SMURF1 gene. This alteration results from a A to T substitution at nucleotide position 1519, causing the asparagine (N) at amino acid position 507 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
