Variant summary

Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PM2BP4_Strong

The NM_001025290.3(DPPA5):c.302A>G(p.Lys101Arg) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000452 in 1,614,100 control chromosomes in the GnomAD database, including 1 homozygotes. In-silico tool predicts a benign outcome for this variant. 15/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. K101Q) has been classified as Uncertain significance.

Genes affected

DPPA5 (HGNC:19201): (developmental pluripotency associated 5) This gene encodes a protein that may function in the control of cell pluripotency and early embryogenesis. Expression of this gene is a specific marker for pluripotent stem cells. Pseudogenes of this gene are located on the short arm of chromosome 10 and the long arm of chromosomes 14 and 19.

Collection Method: clinical testing

The c.302A>G (p.K101R) alteration is located in exon 3 (coding exon 3) of the DPPA5 gene. This alteration results from a A to G substitution at nucleotide position 302, causing the lysine (K) at amino acid position 101 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
