Genes affected
TIMM13 (HGNC:11816): (translocase of inner mitochondrial membrane 13) This gene encodes a member of the evolutionarily conserved TIMM (translocase of inner mitochondrial membrane) family of proteins that function as chaperones in the import of proteins from the cytoplasm into the mitochondrial inner membrane. Proteins of this family play a role in collecting substrate proteins from the translocase of the outer mitochondrial membrane (TOM) complex and delivering them to either the sorting and assembly machinery in the outer mitochondrial membrane (SAM) complex or the TIMM22 complex in the inner mitochondrial membrane. The encoded protein and the translocase of mitochondrial inner membrane 8a protein form a 70 kDa complex in the intermembrane space. [provided by RefSeq, Jul 2013]

Review Status: criteria provided, single submitter
Collection Method: clinical testing

The c.182C>T (p.S61F) alteration is located in exon 2 (coding exon 2) of the TIMM13 gene. This alteration results from a C to T substitution at nucleotide position 182, causing the serine (S) at amino acid position 61 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
