Rady Children's Institute for Genomic Medicine, Rady Children's Hospital San Diego RCV000853294 SCV000996132 likely pathogenic Mitochondrial complex I deficiency 2018-04-18 criteria provided, single submitter clinical testing This variant has not been reported in the Human Gene Mutation Database (HGMD), however a different variant at the same amino acid position, c.383G>T(pArg128Leu), has been reported as disease causing in a patient with Mitochondrial complex I deficiency (PMID: 27290639). Multiple lines of computational evidence predict this change to be damaging. The HGMD database and medical literature have reported several disease causing missense variants located within the same exon in the near by amino acids, suggesting this region of the NDUFV1 gene to be important for the protein function (PMID: 23631824, 26345448). This variant has been reported in the public SNP databases, but with a very low frequency. In addition, the c.383G>A (p.Arg128Gln) change was found to be in trans with another likely pathogenic change, (c.166T>C; p.Ser56Pro), also identified in this patient. Based on the overall evidence, we classified this variant as likely pathogenic.
