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]

The c.167T>A (p.I56N) alteration is located in exon 4 (coding exon 2) of the NDUFC1 gene. This alteration results from a T to A substitution at nucleotide position 167, causing the isoleucine (I) at amino acid position 56 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
