Genes affected

NFU1 (HGNC:16287): (NFU1 iron-sulfur cluster scaffold) This gene encodes a protein that is localized to mitochondria and plays a critical role in iron-sulfur cluster biogenesis. The encoded protein assembles and transfers 4Fe-4S clusters to target apoproteins including succinate dehydrogenase and lipoic acid synthase. Mutations in this gene are a cause of multiple mitochondrial dysfunctions syndrome-1, and pseudogenes of this gene are located on the short arms of chromosomes 1 and 3. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Dec 2011]

The c.727G>A (p.D243N) alteration is located in exon 8 (coding exon 8) of the NFU1 gene. This alteration results from a G to A substitution at nucleotide position 727, causing the aspartic acid (D) at amino acid position 243 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
