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]

Apr 13, 2023

The c.23G>T (p.R8L) alteration is located in exon 3 (coding exon 1) of the NDUFC1 gene. This alteration results from a G to T substitution at nucleotide position 23, causing the arginine (R) at amino acid position 8 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
