Panel Version: 4.143

COX11 variants have been associated with Mitochondrial complex IV deficiency, nuclear type 23 (OMIM:620275), but not with a phenotype in Gen2Phen. At least four COX11 variants have been reported in three unrelated cases of OMIM:620275 (PMIDs: 36030551;38068960), together with supportive functional studies in patient's fibroblasts and Saccharomyces cerevisiae.
