Lactate dehydrogenase B deficiency is a condition that affects how the body breaks down sugar to use as energy in muscle cells. People with this condition typically do not have any signs or symptoms of the condition. They do not have difficulty with physical activity or any specific physical features related to the condition. Affected individuals are usually discovered only when routine blood tests reveal reduced lactate dehydrogenase activity. Lactate dehydrogenase B deficiency is caused by mutations in the LDHB gene. This condition is inherited in an autosomal recessive pattern.[1]
