Isolated cIII deficiency is mainly associated with mutations in mtDNA MTCYB gene (MIM516020), encoding cyt b, or in assembly factor genes (BCS1L�CMIM603647, TTC19�CMIM613814, UQCC2�CMIM614461, and LYRM7�CMIM615831), whereas mutations in nuclear genes coding cIII structural subunits are extremely infrequent. Most of the MTCYB mutations are sporadic and cause a mitochondrial myopathy. cIII disorders due to nuclear mutations have usually an autosomal recessive inheritance pattern with onset at birth. The peculiar clinical features are lactic acidosis, hypotonia, failure to thrive, delayed psychomotor development, NSC 23766 research buy encephalopathy (Ghezzi and Zeviani, 2012; Invernizzi et al., 2013); in some patients visceral involvement as hepatopathy and tubulopathy has been reported (de Lonlay et al., 2001; De Meirleir et al., 2003; Tucker et al., 2013). TTC19 is a mitochondrial protein, embedded in the inner mitochondrial membrane, which has been proposed to have a role in an early step of cIII assembly. Mutations in TTC19 were described for the first time in three Italian individuals from two unrelated families with young-onset characterized by slowly progressive encephalopathy and isolated cIII deficiency, and in a fourth Italian individual with an adult-onset characterized by subacute, rapidly progressive neurological failure and isolated cIII deficiency (Ghezzi et al., 2011).
