Here, we further investigate the association between genetic variants in the NOTCH pathway genes and aortic stenosis in a case–control study of 90 CAVD cases and 4723 controls using target panel sequencing of full-length 20 genes from a NOTCH-related pathway (DVL2, DTX2, MFNG, NUMBL, LFNG, DVL1, DTX4, APH1A, DTX1, APH1B, NOTCH1, ADAM17, DVL3, NCSTN, DTX3L, ILK, RFNG, DTX3, NOTCH4, PSENEN). This evidence concerns the gene DTX1 and congenital bilateral aplasia of vas deferens from CFTR mutation.
