Carl Fratter (Oxford University Hospitals NHS Trust)

I don't know

Updated information and Amber review collated by Carl Fratter May 2019 on behalf of GMS mitochondrial specialist test group: no reports of human disease; complex IV subunit
Created: 10 May 2019, 1:02 p.m.

Mode of inheritance

No OMIM phenotype


  • none found

Ellen McDonagh (Genomics England Curator)

This gene has been demoted to Amber until further evidence is provided. This gene is currently Red on the Mitochondrial disorders panel (code 112, Version 1.151) - further evidence needs to be submitted to support promoting this gene family member to Green.
