Genes affected

SETD1B (HGNC:29187): (SET domain containing 1B, histone lysine methyltransferase) SET1B is a component of a histone methyltransferase complex that produces trimethylated histone H3 at Lys4 (Lee et al., 2007 [PubMed 17355966]).[supplied by OMIM, Mar 2008]

SETD1B Gene-Disease associations (from GenCC):

• complex neurodevelopmental disorder

  Inheritance: AD Classification: DEFINITIVE Submitted by: ClinGen
• intellectual developmental disorder with seizures and language delay

  Inheritance: AD Classification: STRONG, MODERATE Submitted by: Ambry Genetics, Labcorp Genetics (formerly Invitae), PanelApp Australia, G2P

ACMG classification
