Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the PPT2 gene is commonly pathogenic or not.

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.

• Function: FUNCTION: Removes thioester-linked fatty acyl groups from various substrates including S-palmitoyl-CoA. Has the highest S- thioesterase activity for the acyl groups palmitic and myristic acid followed by other short- and long-chain acyl substrates. However, because of structural constraints, is unable to remove palmitate from peptides or proteins. {ECO:0000269|PubMed:10417332, ECO:0000269|PubMed:12855696, ECO:0000269|PubMed:9341199}.
