T2  - Syndromes: Rapid Recognition and Perioperative Implications
AB  - Complex  II  is,  as  in  Complex  I,  caused  by  mutations  in  nDNA.  This  mutation  is  defined  as  a  “direct  hit"  in  the  genes  that  encode  subunits  of  respiratory  chains  complexes.  It  affects  the  enzyme  succinate  CoQ  reductase  which  is  responsible  for  the  transfer  of  electrons  by  the  reduction  of  succinate  to  fumarate  in  the  electron  chain  pathway  (see  Table  C-2).  Deficiency  of  complex  II  is  characterized  by  highly  variable  phenotypic  expression.  The  clinical  features  include  encephalomyopathy,  failure  to  thrive,  severe  developmental  delay,  muscle  hypotonia,  lethargy,  respiratory  failure,  ataxia,  and  myoclonic  seizures.  The  presence  of  lactic  acidosis  is  common.  The  most  frequent  clinical  condition  is  Leigh  syndrome.  See  Table  C-4.
