Mitochondrial DNA depletion syndrome, encephalomyopathic form with renal tubulopathy

What it is

A rare mitochondrial DNA depletion syndrome characterized by neonatal or infantile onset of hypotonia, failure to thrive, global developmental delay, and persistent lactic acidosis. The disease course is variable and ranges from intractable diarrhea and respiratory failure with fatal outcome in early infancy to a milder phenotype with survival into childhood. Additional reported features include sensorineural hearing loss, microcephaly, seizures, pigmentary retinopathy, and renal tubulopathy.

Disease

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.
