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.

The c.440C>T (p.A147V) alteration is located in exon 4 (coding exon 4) of the DPPA3 gene. This alteration results from a C to T substitution at nucleotide position 440, causing the alanine (A) at amino acid position 147 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
