Genes affected
NDUFC1 (HGNC:7705): (NADH:ubiquinone oxidoreductase subunit C1) The encoded protein is a subunit of the NADH:ubiquinone oxidoreductase (complex I), the first enzyme complex in the electron transport chain located in the inner mitochondrial membrane. 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 28, 2023The c.14C>G (p.A5G) alteration is located in exon 3 (coding exon 1) of the NDUFC1 gene. This alteration results from a C to G substitution at nucleotide position 14, causing the alanine (A) at amino acid position 5 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
