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]

The c.1478G>A (p.R493H) alteration is located in exon 6 (coding exon 6) of the CPEB4 gene. This alteration results from a G to A substitution at nucleotide position 1478, causing the arginine (R) at amino acid position 493 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
