Other highly enriched genes for nsDNV—KMT2D (OMIM 147920), KMT2A (OMIM 605130), NSD1 (OMIM 117550), TAB2 (OMIM 614980), and ADNP (OMIM 615873)—have been previously associated with different types of neurodevelopmental disorders with co-occurrence of CHD. This evidence concerns the gene NSD1 and neurodevelopmental disorder.
