Variant chr21-44109039-A-G details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Likely benign. Variant got -1 ACMG points: 0P and 1B. BP4

The NM_005049.3(PWP2):c.74A>G(p.Asp25Gly) variant causes a missense change involving the alteration of a conserved nucleotide. In-silico tool predicts 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. D25N) has been classified as Likely benign.

Genes affected

PWP2 (HGNC:9711): (PWP2 small subunit processome component) Enables RNA binding activity. Predicted to be involved in maturation of SSU-rRNA from tricistronic rRNA transcript (SSU-rRNA, 5.8S rRNA, LSU-rRNA) and ribosomal small subunit assembly. Predicted to be located in nucleoplasm. Predicted to be part of Pwp2p-containing subcomplex of 90S preribosome and small-subunit processome. [provided by Alliance of Genome Resources, Apr 2022]

Ambry Genetics

Feb 12, 2024

The c.74A>G (p.D25G) alteration is located in exon 2 (coding exon 2) of the PWP2 gene. This alteration results from a A to G substitution at nucleotide position 74, causing the aspartic acid (D) at amino acid position 25 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
