Genes affected
CREB1 (HGNC:2345): (cAMP responsive element binding protein 1) This gene encodes a transcription factor that is a member of the leucine zipper family of DNA binding proteins. This protein binds as a homodimer to the cAMP-responsive element, an octameric palindrome. The protein is phosphorylated by several protein kinases, and induces transcription of genes in response to hormonal stimulation of the cAMP pathway. Alternate splicing of this gene results in several transcript variants encoding different isoforms. [provided by RefSeq, Mar 2016]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 28, 2022The c.137C>T (p.A46V) alteration is located in exon 3 (coding exon 2) of the CREB1 gene. This alteration results from a C to T substitution at nucleotide position 137, causing the alanine (A) at amino acid position 46 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
