Outline of Final Research Achievements

For the safety management of brest milk jaundice (BMJ), I performed analysis UGT1A1 gene in infants with BMJ. I revealed UGT1A1*6 (p.G71R) variant which is a genetic cause of BMJ is also important cause for Gilbert syndrome (Maruo Y. J Pediatr 2016). UGT1A1*28 which is other important variant was also the cause of Gilbert syndrome but not a cause of BMJ. UGT1A1*6 is also the genetic cause of BMJ in low birth weight infants (Yanagi T. J Pediatr 2017) and a risk factor kernicteric in extreme preterm indants (Yanagi T. submitted).
I made p.G71R-humanized UGT1A mice in collaboration with Prof. Tukey in University of California San Diego. The mice will be brought to our laboratory and I continue further study.

Academic Significance and Societal Importance of the Research Achievements

母乳性黄疸は後期新生児期にみられる母乳栄養に関連する遷延性高ビリルビン血症である。多くの赤ちゃんにみられ、核黄疸の危険性がある場合もある。そのため母乳性黄疸の背景を明らかにして、管理法を確立することは子育てをする家族や赤ちゃん自身の健康に寄与する。また、超早産児の核黄疸発生を予防するための研究にもつながり、社会に広く貢献するものと考える。
