The first Korean cases of combined oxidative phosphorylation deficiency 35 with two novel TRIT1 mutations in two siblings confirmed by clinical and molecular investigation

Background Combined oxidative phosphorylation deficiency 35 (COXPD 35) is a very rare autosomal recessive disorder caused by homozygous or compound heterozygous mutations in the TRIT1 gene on chromosome 1p34. Only six cases of COXPD 35 and six allelic variants of TRIT1 gene mutations have been reported worldwide.
