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]

May 11, 2022

The c.218T>C (p.V73A) alteration is located in exon 3 (coding exon 3) of the PWP2 gene. This alteration results from a T to C substitution at nucleotide position 218, causing the valine (V) at amino acid position 73 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
