Variants in the Imprinted IGF2 Gene: A Review and Phasing of De Novo Variants Using Long-Read Sequencing.
Pathogenic variants on the paternal allele of IGF2 are linked to Silver-Russell syndrome (SRS). This report describes two unrelated individuals-a 5-year-old girl and an adult female-with de novo IGF2 missense variants, both diagnosed with SRS. While one exhibited normal development, the other had intellectual disabilit...
