Mitochondrial complex IV deficiency nuclear type 6 (MC4DN6) is an autosomal recessive multisystem metabolic disorder with a highly variable phenotype. Some patients present in the neonatal period with encephalomyopathic features, whereas others present later in the first year of life with developmental regression. Manifestations include hypotonia, feeding difficulties, and global developmental delay. Many, but not all, patients develop hypertrophic cardiomyopathy, which may result in early death. Additional more variable features may include poor overall growth, microcephaly, seizures, neurodegeneration, spasticity, visual defects, retinopathy, and hepatic steatosis. Brain imaging in some patients shows features consistent with Leigh syndrome.

More than 5 unrelated families reported. HCM is prominent, onset variable, including neonatal cases. One baby reported to be microcephalic at birth.
