Genes affected

CPEB3 (HGNC:21746): (cytoplasmic polyadenylation element binding protein 3) Enables mRNA 3'-UTR binding activity and translation factor activity, RNA binding. Involved in cellular response to amino acid stimulus; negative regulation of transcription by RNA polymerase II; and positive regulation of mRNA catabolic process. Located in several cellular components, including cytosol; midbody; and nucleoplasm. Part of CCR4-NOT complex. [provided by Alliance of Genome Resources, Apr 2022]

The c.1478A>G (p.E493G) alteration is located in exon 7 (coding exon 6) of the CPEB3 gene. This alteration results from a A to G substitution at nucleotide position 1478, causing the glutamic acid (E) at amino acid position 493 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
