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]
C1QTNF7-AS1 (HGNC:40683): (C1QTNF7 antisense RNA 1)

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 04, 2022The c.2086C>G (p.L696V) alteration is located in exon 4 (coding exon 4) of the CPEB2 gene. This alteration results from a C to G substitution at nucleotide position 2086, causing the leucine (L) at amino acid position 696 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
