Genes affected

CPEB1 (HGNC:21744): (cytoplasmic polyadenylation element binding protein 1) This gene encodes a member of the cytoplasmic polyadenylation element binding protein family. This highly conserved protein binds to a specific RNA sequence, called the cytoplasmic polyadenylation element, found in the 3' untranslated region of some mRNAs. The encoded protein functions in both the cytoplasm and the nucleus. It is involved in the regulation of mRNA translation, as well as processing of the 3' untranslated region, and may play a role in cell proliferation and tumorigenesis. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2014]

The c.325C>G (p.R109G) alteration is located in exon 3 (coding exon 3) of the CPEB1 gene. This alteration results from a C to G substitution at nucleotide position 325, causing the arginine (R) at amino acid position 109 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
