Genes affected

CRTC3 (HGNC:26148): (CREB regulated transcription coactivator 3) This gene is a member of the CREB regulated transcription coactivator gene family. This family regulates CREB-dependent gene transcription in a phosphorylation-independent manner and may be selective for cAMP-responsive genes. The protein encoded by this gene may induce mitochondrial biogenesis and attenuate catecholamine signaling in adipose tissue. A translocation event between this gene and Notch coactivator mastermind-like gene 2, which results in a fusion protein, has been reported in mucoepidermoid carcinomas. Alternative splicing results in multiple transcript variants that encode different protein isoforms. [provided by RefSeq, Jul 2012]

The c.1150C>T (p.R384W) alteration is located in exon 11 (coding exon 11) of the CRTC3 gene. This alteration results from a C to T substitution at nucleotide position 1150, causing the arginine (R) at amino acid position 384 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
