Genes affected

TSR2 (HGNC:25455): (TSR2 ribosome maturation factor) The protein encoded by this gene appears to repress the transcription of NF-kappaB and may be involved in apoptosis. Defects in this gene are a cause of Diamond-Blackfan anemia. [provided by RefSeq, Oct 2016]

TSR2 Gene-Disease associations (from GenCC):

• Diamond-Blackfan anemia

  Inheritance: AD Classification: SUPPORTIVE Submitted by: Orphanet
• Diamond-Blackfan anemia 14 with mandibulofacial dysostosis

  Inheritance: XL Classification: LIMITED Submitted by: Ambry Genetics, Labcorp Genetics (formerly Invitae)

ACMG classification
