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]
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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 02, 2022The c.610C>G (p.H204D) alteration is located in exon 6 (coding exon 6) of the TMCO6 gene. This alteration results from a C to G substitution at nucleotide position 610, causing the histidine (H) at amino acid position 204 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
