Genes affected

CPEB4 (HGNC:21747): (cytoplasmic polyadenylation element binding protein 4) Enables RNA binding activity. Predicted to be involved in several processes, including cellular response to glucose starvation; negative regulation of cytoplasmic translation; and response to ischemia. Located in cytoplasm and nucleus. Biomarker of liver cirrhosis; portal hypertension; and primary biliary cholangitis. [provided by Alliance of Genome Resources, Apr 2022]

Ambry Genetics

Oct 26, 2021

The c.1045G>T (p.A349S) alteration is located in exon 1 (coding exon 1) of the CPEB4 gene. This alteration results from a G to T substitution at nucleotide position 1045, causing the alanine (A) at amino acid position 349 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
