Genes affected

NDUFAF6 (HGNC:28625): (NADH:ubiquinone oxidoreductase complex assembly factor 6) This gene encodes a protein that localizes to mitochondria and contains a predicted phytoene synthase domain. The encoded protein plays an important role in the assembly of complex I (NADH-ubiquinone oxidoreductase) of the mitochondrial respiratory chain through regulation of subunit ND1 biogenesis. Mutations in this gene are associated with complex I enzymatic deficiency. [provided by RefSeq, Nov 2011]

The c.485dupA (p.N162Kfs*4) alteration, located in exon 5 (coding exon 5) of the NDUFAF6 gene, consists of a duplication of A at position 485, causing a translational frameshift with a predicted alternate stop codon after 4 amino acids. This alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. Based on the available evidence, this alteration is classified as pathogenic. -
