Glycogen storage disease due to lactate dehydrogenase deficiency

Disease definition

A rare genetic glycogen storage disease characterized by either lactate dehydrogenase (LDH) M- or H-subunit deficiency. Main features of LDH M-subunit deficiency are exertional fatigue and muscle pain potentially accompanied by myoglobinuria. Some patients may develop pustular psoriasis-like skin lesions. Complications of pregnancy, such as frequent abdominal pains and increased uterine tone with a risk of dystocia have also been described. LDH H-subunit deficiency manifests with low serum LDH activity of unclear clinical relevance.
