Combined oxidative phosphorylation defect type 24

What it is

Combined oxidative phosphorylation defect type 24 is a rare mitochondrial oxidative phosphorylation disorder characterized by variable phenotype, including developmental delay with psychomotor regression, intellectual disability, epilepsy, Leigh syndrome, non-syndromic hearing loss, visual impairment and severe myopathy. Decreased activity of mitochondrial respiratory complexes and lactic acidosis are common findings, and diffuse cerebral atrophy may be associated.

Prevalence figures describe populations, not individuals, and are often estimates from a single study. Where the figure is an incidence or a birth prevalence, it says so.

ICD-10 codes

ICD-10 has no distinct code for most rare diseases, so many are filed under the nearest available one. A shared code identifies the group, not this disease — the ORPHAcode above is what identifies it.

Reached through the ICD-10 categories this disease is filed under, so these describe the broader group rather than this disease specifically.
