Genes affected

CREB5 (HGNC:16844): (cAMP responsive element binding protein 5) The product of this gene belongs to the CRE (cAMP response element)-binding protein family. Members of this family contain zinc-finger and bZIP DNA-binding domains. The encoded protein specifically binds to CRE as a homodimer or a heterodimer with c-Jun or CRE-BP1, and functions as a CRE-dependent trans-activator. Alternatively spliced transcript variants encoding different isoforms have been identified. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Uncertain_significance. Variant got 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage

The c.413C>T (p.P138L) alteration is located in exon 5 (coding exon 5) of the CREB5 gene. This alteration results from a C to T substitution at nucleotide position 413, causing the proline (P) at amino acid position 138 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
