Genes affected

TIMM10 (HGNC:11814): (translocase of inner mitochondrial membrane 10) The mitochondrial protein encoded by this gene 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, functioning as intermembrane space chaperones for the highly insoluble carrier proteins.

ACMG classification

Verdict is Uncertain_significance. Variant got 3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.771

Collection Method: clinical testing

The c.186T>G (p.H62Q) alteration is located in exon 3 (coding exon 2) of the TIMM10 gene. This alteration results from a T to G substitution at nucleotide position 186, causing the histidine (H) at amino acid position 62 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
