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 GeneticsFeb 06, 2024The c.544G>A (p.A182T) alteration is located in exon 5 (coding exon 5) of the TMCO6 gene. This alteration results from a G to A substitution at nucleotide position 544, causing the alanine (A) at amino acid position 182 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
