Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the ATG4A gene is commonly pathogenic or not. These statistics are base on transcript: NM_000052936.5. 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.

• Function: FUNCTION: Cysteine protease required for the cytoplasm to vacuole transport (Cvt) and autophagy. Cleaves the C-terminal amino acid of ATG8 family proteins to reveal a C-terminal glycine. Exposure of the glycine at the C-terminus is essential for ATG8 proteins conjugation to phosphatidylethanolamine (PE) and insertion to membranes, which is necessary for autophagy. Preferred substrate is GABARAPL2 followed by MAP1LC3A and GABARAP. Has also an activity of delipidating enzyme for the PE-conjugated forms. {ECO:0000269|PubMed:12473658, ECO:0000269|PubMed:15169837, ECO:0000269|PubMed:17347651, ECO:0000269|PubMed:21177865, ECO:0000269|PubMed:21245471, ECO:0000269|PubMed:22302004}.
