COMBINED OXIDATIVE PHOSPHORYLATION DEFECT TYPE 20
Alternate names
COMBINED OXIDATIVE PHOSPHORYLATION DEFECT TYPE 20 Is also known as coxpd20
Description
Combined oxidative phosphorylation defect type 20 is a rare mitochondrial oxidative phosphorylation disorder characterized by variable combination of psychomotor delay, hypotonia, muscle weakness, seizures, microcephaly, cardiomyopathy and mild dysmorphic facial features. Variable types of structural brain anomalies have also been reported. Biochemical studies typically show decreased activity of mitochondrial complexes (mainly complex I).
Most common symptoms of COMBINED OXIDATIVE PHOSPHORYLATION DEFECT TYPE 20
- Seizures
- Global developmental delay
- Generalized hypotonia
- Microcephaly
- Ataxia
