Tóm tắt

AbstractWe investigated two siblings of a Spanish family presenting with congenital lactic acidosis. They had severe failure to thrive, liver dysfunction, and renal tubulopathy. An isolated biochemical complex III deficiency was detected in liver. A search for mutations in the human bc1 synthesis like (BCS1L) gene was undertaken. Direct sequencing revealed a missense mutation R45C and a nonsense mutation R56X, both located in exon 1 of BCS1L. The missense mutation in combination with a loss of function of the second allele is responsible for the isolated complex III deficiency in this family. © 2003 Wiley‐Liss, Inc.
