Primary Mitochondrial Disease
- Mitochondrial Respiratory Chain Complex Deficiency
One of 61 genes linked to it
Isolated deficiencies of complex I, II, III, IV or V, caused by variants in nuclear or mitochondrial genes, which can affect the brain, muscles, heart, liver and other energy-demanding organs.
- 2 GenCC submitters rate it definitive or strong
What knowing changes
Knowing can end a diagnostic search and guide surveillance of affected organs and avoidance of drugs toxic to mitochondria.
How NDUFAF4 is laid out
- Coding sequence
- Untranslated region
- Intron
- Direction of transcription
- Known disease-causing sites
- Stretches short reads find hard
Exons of the gene's MANE Select transcript (release v1.5), from NCBI and EMBL-EBI, on the GRCh38 reference genome.
Chromosome bands from UCSC's GRCh38 ideogram (2022-10-29).
Nearby genes from Ensembl release 116, on GRCh38.
Exons make up 2.4 kb of the gene's 8.6 kb; 528 of those bases code for the protein.
How a genome test reads NDUFAF4
1
position in NDUFAF4 where ClinVar classes a change as pathogenic or likely pathogenic
None of them falls in a region short reads find hard.
A whole genome covers all 8.6 kb of NDUFAF4, introns included, not only the 2.4 kb of exons.
