Genes affected

CPEB2 (HGNC:21745): (cytoplasmic polyadenylation element binding protein 2) The protein encoded by this gene is highly similar to cytoplasmic polyadenylation element binding protein (CPEB), an mRNA-binding protein that regulates cytoplasmic polyadenylation of mRNA as a trans factor in oogenesis and spermatogenesis. Studies of the similar gene in mice suggested a possible role of this protein in transcriptionally inactive haploid spermatids. Alternatively spliced transcript variants encoding distinct isoforms have been described. [provided by RefSeq, Jul 2008]

The c.2707A>G (p.M903V) alteration is located in exon 11 (coding exon 11) of the CPEB2 gene. This alteration results from a A to G substitution at nucleotide position 2707, causing the methionine (M) at amino acid position 903 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
