Abstract


We descripe three patients with SRNS associated with pathogentic changes in two CoQ pathway genes: one novel homozygous COQ2 variant was identified in two cousins with adolescent-onset SRNS and mild neurological symptoms (Family 1); and one novel COQ6 variant was found in a child with early onset SRNS without deafness and neurological involvement (Family 2). (A, B) : families (C) : Sanger sequencing showing COQ2 change: NM_015697.7: c.1169G>C; NP_056512.5; p.Gly390Ala (c.1019G>C; p.Gly340Ala, according to KU877220 GenBank sequence) (D) : Sanger sequencing showing COQ6 change: NM_182476.2:c.782C>T; NP_872282.1:p.Pro261Leu. (E, F): Functional complementation in yeast. Serial dilutions of DeltaCOQ2 and DeltaCOQ6 yeast transformed with wild-type, the empty vector and the mutant alleles; complex II+III (C.II+C.III) and citrate synthase (CS) activities.
