Purpose : Wilson`s disease is an autosomal recessive disorder characterized by copper accumulation in the liver, brain, and other organs due to defected copper metabolism. The incidence of Wilson`s disease is approximately one in 30,000 population in the world, more common than phenylketonuria in Korea. The early diagnosis or presymptomatic diagnosis of Wilson`s disease is critical in order for them... |

Methods : One hundred... |
Purpose : Extrahepatic biliary atresia is the most common indication for liver transplantation in children, but the etiology of this disorders remains unknown. It would be very signficant to identify genes that are specifically expressed in pathologic liver tissue of biliary atresia and analyze the pattern of expression in those genes. Methods : We made dot blot panels consisting of 1,730 different EST(expressed sequence... |

Purpose : Developmental delay is a fairly common problem in childhood and its early diagnosis is crucial not only for the child but also for the family and society. If found early and properly managed, the side effects can be minimized and the child with developmental delay will have a better prognosis. However, early diagnosis is difficult due to various... |
Purpose : The urinary mass screening program for the detection of proteinuria had been performed for a school age population in the city of Seoul since 1981. However, systematic evaluation for this program had never been done. We, therefore, designed a systematic evaluation in corporation with the Seoul School Health Center for students with proteinuria identified in the mass screening to determine the prevalence... |

We have experienced 4 and 5-week-old male neonates presented low T4 and normal TSH l-evel by filter paper mothod for neonatal screening, finally diagnosed typical TDG deficiency wit h TBG radioimmunoassay, paper electrophoresis, and autoradiography. Two neonates have ha d no specific complaints and lived well until now. Congenital TBG deficiency is an X chromosome linked inhcritant disorder characterized by l... |
Mental retardation(MR) is classically deficits in adaptive behavior and manifest during the developmental period. The causes of mental retardation were not understood in many cases. This study was undertaken to identify the etiologies of mentally retarded children enrolled in a special educational institution under the hypothesis that clarifying causes of MR can not only provide basic epidemiological data on MR in... |
In 1,146 term neonates without perinatal problems who were born in kwangju Christian Hospital, blood TSH levels were measured by immunoradiometric assay.

Five years ago, we made the cut-off value of TSH by dry filter paper method as 15μU/ml to screening congenital hypothyrodism. Since then, 1,210 term neonates, who had no perinatal problems, screening test with this cut-off point. Neonates had been recalled for measurement of serum T4/TSH to rule out congenital hypothyroidism if their TSH value by screening tests reveal more... |
In Korea, the study of inborn errors of metabolism is very primitive. Even the incidence and prevalence of the disease of inborn errors of metabolism are not known in Korea. We have done this study of inborn errors of metabolism in Korea and concluded that: 1) The varieties and incidences of inborn errors of metabolism in Korea might be relatively diverse and high. 2) Nation wide mandatory... |
