• hereditary hypofibrinogenemia
  6 August 2007

  Definition: Hypofibrinogenemia is a rare inherited disorder characterized by low levels of circulating fibrinogen, caused by mutations within 1 of the 3 fibrinogen genes.
  Etiology
  As hereditary afibrinogenemia, hereditary hypofibrinogenemia is the result of mutation in one or another of the 3 fibrinogen genes, alpha (FGA) (MIM.134820), beta (FGB) (MIM.134830), or gamma (FGG) (MIM.134850).
  Complete absence of detectable fibrinogen, true congenital afibrinogenemia, was first demonstrated (...)

• IL12B
  31 August 2004

  The IL12B gene on chromosome 5q31-33 encodes the p40 subunit of interleukin 12, an immunomodulatory cytokine.
  Interleukin-12 has 2 chains, a 35-kD chain encoded by IL12A (MIM.161560) and a 40-kD chain encoded by IL12B.

• F12
  15 December 2007

  The coding sequence of F12 consists of multiple domains that are homologous to domains found in fibronectin (MIM.135600) and tissue-type plasminogen activator (tTPA) (MIM.173370).
  These regions are found as separate exons in the gene. The 5-prime end of the gene does not contain the typical TATA and CAAT sequences found in other genes. This is consistent with the finding that transcription of the gene is initiated at multiple sites.

• neonatal diabetes mellitus
  29 July 2007

  Transient (TNDM) and Permanent (PNDM) Neonatal Diabetes Mellitus are rare conditions occurring in 1:300,000-400,000 live births. TNDM infants develop diabetes in the first few weeks of life but go into remission in a few months, with possible relapse to a permanent diabetes state usually around adolescence or as adults.
  The pancreatic dysfunction in this condition may be maintained throughout life, with relapse initiated at times of metabolic stress such as puberty or pregnancy.
  In PNDM, (...)
