Genes affected

CREB3L2 (HGNC:23720): (cAMP responsive element binding protein 3 like 2) This gene encodes a member of the oasis bZIP transcription factor family. Members of this family can dimerize but form homodimers only. The encoded protein is a transcriptional activator. Translocations between this gene on chromosome 7 and the gene fused in sarcoma on chromosome 16 can be found in some tumors. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2011]

ACMG classification

Verdict is Uncertain_significance. Variant got 4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.903

The c.911A>G (p.N304S) alteration is located in exon 6 (coding exon 6) of the CREB3L2 gene. This alteration results from a A to G substitution at nucleotide position 911, causing the asparagine (N) at amino acid position 304 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
