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

Aug 19, 2023

The c.1124C>T (p.P375L) alteration is located in exon 1 (coding exon 1) of the CPEB4 gene. This alteration results from a C to T substitution at nucleotide position 1124, causing the proline (P) at amino acid position 375 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
