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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 30, 2023The c.251T>C (p.L84P) alteration is located in exon 4 (coding exon 4) of the PWP2 gene. This alteration results from a T to C substitution at nucleotide position 251, causing the leucine (L) at amino acid position 84 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
