Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the PPIL1 gene is commonly pathogenic or not. These statistics are base on transcript: NM_000016059.5. Only rare variants are included in the table.

In the table, we include only reliable ClinVar variants with their consequences to MANE Select, Mane Plus Clinical transcripts, or transcripts with TSL equals 1. Click the count to view the source variants.

Warning: slight differences between displayed counts and the number of variants in ClinVar may occur, primarily due to (1) the application of a different transcript and/or consequence by our variant effect predictor or (2) differences in clinical significance: we classify Benign/Likely benign variants as Likely benign and Pathogenic/Likely pathogenic variants as Likely pathogenic.

Effect	Pathogenic	Likely pathogenic	VUS	Likely benign	Benign	Sum

• Function: FUNCTION: Involved in pre-mRNA splicing as component of the spliceosome (PubMed:11991638, PubMed:28502770, PubMed:28076346). PPIases accelerate the folding of proteins. It catalyzes the cis- trans isomerization of proline imidic peptide bonds in oligopeptides (PubMed:16595688). {ECO:0000269|PubMed:11991638, ECO:0000269|PubMed:16595688, ECO:0000269|PubMed:28076346, ECO:0000269|PubMed:28502770}.
