Genes affected
NDUFV2 (HGNC:7717): (NADH:ubiquinone oxidoreductase core subunit V2) The NADH-ubiquinone oxidoreductase complex (complex I) of the mitochondrial respiratory chain catalyzes the transfer of electrons from NADH to ubiquinone, and consists of at least 43 subunits. The complex is located in the inner mitochondrial membrane. This gene encodes the 24 kDa subunit of complex I, and is involved in electron transfer. Mutations in this gene are implicated in Parkinson's disease, bipolar disorder, schizophrenia, and have been found in one case of early onset hypertrophic cardiomyopathy and encephalopathy. A non-transcribed pseudogene of this locus is found on chromosome 19. [provided by RefSeq, Oct 2009]

The c.11C>T (p.S4F) alteration is located in exon 1 (coding exon 1) of the NDUFV2 gene. This alteration results from a C to T substitution at nucleotide position 11, causing the serine (S) at amino acid position 4 to be replaced by a phenylalanine (F). The p.S4F alteration is predicted to be tolerated by in silico analysis. Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
