Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the APOC4-APOC2 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.

Variant type	Pathogenic	Likely pathogenic	VUS	Likely benign	Benign	Sum
synonymous				19		19
missense	2		24	8		34
nonsense	5	1				6
start loss						0
frameshift	5					5
inframe indel						0
splice donor/acceptor (+/-2bp)	1		2	1	1	5
splice region						0
non coding			11	12	10	33
Total	13	1	37	40	11

Highest pathogenic variant AF is 0.0000329
