Genes affected
DPPA3 (HGNC:19199): (developmental pluripotency associated 3) This gene encodes a protein that in mice may function as a maternal factor during the preimplantation stage of development. In mice, this gene may play a role in transcriptional repression, cell division, and maintenance of cell pluripotentiality. In humans, related intronless loci are located on chromosomes 14 and X.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 31, 2023The c.157G>C (p.V53L) alteration is located in exon 2 (coding exon 2) of the DPPA3 gene. This alteration results from a G to C substitution at nucleotide position 157, causing the valine (V) at amino acid position 53 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
