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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 10, 2021The c.50G>A (p.S17N) alteration is located in exon 1 (coding exon 1) of the CPEB2 gene. This alteration results from a G to A substitution at nucleotide position 50, causing the serine (S) at amino acid position 17 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
