MSUD is a hereditary metabolic disorder that is characterized by impaired activity of the BCKADC . Liver transplantation has been approved as a treatment for some MSUD cases in which the control of BCAA s is insufficient. Although there have been several reports about DDLT for MSUD , few LDLT cases have been reported. Because either of parents who are heterozygote of this disease usually applies to be a candidate of donor in LDLT , the impairment of BCKADC activity of graft liver should be concerned. We performed LDLT for 10 month‐old girl with a left lateral segment graft from her father. BCKADC activities of the patient and her parents were measured using lysates of lymphocytes isolated from peripheral blood specimen before the transplant. As a consequence, the activity of BCKADC of father was not inferior to a normal range. The patient tolerated the operation well. Postoperative course was uneventful and mixed milk was started at 8th POD. The serum BCAA s levels have remained within normal range. It should be necessary to follow the physical growth and mental development of the recipient in the future.
