Genes affected

TIMM9 (HGNC:11819): (translocase of inner mitochondrial membrane 9) TIMM9 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]

TIMM9 links:

TOMM20L (HGNC:33752): (translocase of outer mitochondrial membrane 20 like) Predicted to enable mitochondrion targeting sequence binding activity. Predicted to contribute to protein transmembrane transporter activity. Predicted to be involved in protein import into mitochondrial matrix and tRNA import into mitochondrion. Predicted to be integral component of membrane. Predicted to be part of mitochondrial outer membrane translocase complex. Predicted to be integral component of mitochondrial outer membrane.

Ambry Genetics

Jan 23, 2024

The c.200T>G (p.F67C) alteration is located in exon 6 (coding exon 3) of the TIMM9 gene. This alteration results from a T to G substitution at nucleotide position 200, causing the phenylalanine (F) at amino acid position 67 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
