Variants in the Imprinted IGF2 Gene: A Review and Phasing of De Novo Variants Using Long-Read Sequencing.
It is demonstrated that long-read sequencing can determine the allelic origin of de novo IGF2 variants using differentially methylated regions, eliminating the need for parental samples, and confirms long-read sequencing as a powerful tool for identifying de novo variant origins in imprinted genes like IGF2.
