Genes affected

CREG1 (HGNC:2351): (cellular repressor of E1A stimulated genes 1) The adenovirus E1A protein both activates and represses gene expression to promote cellular proliferation and inhibit differentiation. The protein encoded by this gene antagonizes transcriptional activation and cellular transformation by E1A. This protein shares limited sequence similarity with E1A and binds both the general transcription factor TBP and the tumor suppressor pRb in vitro. This gene may contribute to the transcriptional control of cell growth and differentiation. [provided by RefSeq, Jul 2008]

The c.647A>T (p.N216I) alteration is located in exon 3 (coding exon 3) of the CREG1 gene. This alteration results from a A to T substitution at nucleotide position 647, causing the asparagine (N) at amino acid position 216 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
