Genes affected
TSFM (HGNC:12367): (Ts translation elongation factor, mitochondrial) This gene encodes a mitochondrial translation elongation factor. The encoded protein is an enzyme that catalyzes the exchange of guanine nucleotides on the translation elongation factor Tu during the elongation step of mitchondrial protein translation. Mutations in this gene are associated with combined oxidative phosphorylation deficiency-3 syndrome. Alternate splicing results in multiple transcript variants.[provided by RefSeq, Mar 2010]
TSFM Gene-Disease associations (from GenCC):
  • fatal mitochondrial disease due to combined oxidative phosphorylation defect type 3
    Inheritance: AR Classification: STRONG, SUPPORTIVE Submitted by: Orphanet, Labcorp Genetics (formerly Invitae)
  • Leigh syndrome
