Genes affected

TIMM10B (HGNC:4022): (translocase of inner mitochondrial membrane 10B) FXC1, or TIMM10B, belongs to a family of evolutionarily conserved proteins that are organized in heterooligomeric complexes in the mitochondrial intermembrane space. These proteins mediate the import and insertion of hydrophobic membrane proteins into the mitochondrial inner membrane.[supplied by OMIM, Apr 2004]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.190A>C (p.M64L) alteration is located in exon 3 (coding exon 3) of the TIMM10B gene. This alteration results from a A to C substitution at nucleotide position 190, causing the methionine (M) at amino acid position 64 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
