Genes affected

CITED2 (HGNC:1987): (Cbp/p300 interacting transactivator with Glu/Asp rich carboxy-terminal domain 2) The protein encoded by this gene inhibits transactivation of HIF1A-induced genes by competing with binding of hypoxia-inducible factor 1-alpha to p300-CH1. Mutations in this gene are a cause of cardiac septal defects. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, May 2012]

CITED2 Gene-Disease associations (from GenCC):

• atrial septal defect 8

  Inheritance: AD Classification: MODERATE Submitted by: Laboratory for Molecular Medicine
• congenital heart defects, multiple types

  Inheritance: AD Classification: MODERATE Submitted by: Ambry Genetics
• ventricular septal defect 2

  Inheritance: Unknown Classification: LIMITED Submitted by: Labcorp Genetics (formerly Invitae)

ENSG00000226571 (HGNC:):

ACMG classification

Our verdict: Likely_pathogenic. The variant received 6 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
