Variants pathogenicity by type
Statistics on ClinVar variants can assist in determining whether a specific variant type in the APH1A 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: Non-catalytic subunit of the gamma-secretase complex, an endoprotease complex that catalyzes the intramembrane cleavage of integral membrane proteins such as Notch receptors and APP (amyloid-beta precursor protein) (PubMed:12297508, PubMed:12522139, PubMed:12763021, PubMed:12679784, PubMed:25043039, PubMed:26280335). Required for normal gamma- secretase assembly (PubMed:12522139, PubMed:12471034, PubMed:12763021, PubMed:19369254). The gamma-secretase complex plays a role in Notch and Wnt signaling cascades and regulation of downstream processes via its role in processing key regulatory proteins, and by regulating cytosolic CTNNB1 levels (Probable). {ECO:0000269|PubMed:12297508, ECO:0000269|PubMed:12471034, ECO:0000269|PubMed:12522139, ECO:0000269|PubMed:12679784, ECO:0000269|PubMed:12763021, ECO:0000269|PubMed:25043039, ECO:0000269|PubMed:26280335, ECO:0000305}.;
