Variant summary

Our verdict is Uncertain significance. The variant received 3 ACMG points: 3P and 0B. PM2PP3

The NM_018502.5(TMCO6):c.610C>T(p.His204Tyr) variant causes a missense change. The variant allele was found at a frequency of 0.0000118 in 1,614,114 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. H204D) has been classified as Uncertain significance.

Genes affected

TMCO6 (HGNC:28814): (transmembrane and coiled-coil domains 6) Predicted to enable nuclear import signal receptor activity. Predicted to be involved in protein import into nucleus. Predicted to be integral component of membrane. [provided by Alliance of Genome Resources, Apr 2022]

TMCO6 links:

NDUFA2 (HGNC:7685): (NADH:ubiquinone oxidoreductase subunit A2) The encoded protein is a subunit of the hydrophobic protein fraction of the NADH:ubiquinone oxidoreductase (complex 1), the first enzyme complex in the electron transport chain located in the inner mitochondrial membrane, and may be involved in regulating complex I activity or its assembly via assistance in redox processes. Mutations in this gene are associated with Leigh syndrome, an early-onset progressive neurodegenerative disorder. Alternative splicing results in multiple transcript variants.[provided by RefSeq, May 2010]
