Epidemiology and Disease Associations
McLeod syndrome is present in 0.5 to 1 per 100,000 the population. McLeod males have variable acanthocytosis due to a defect in the inner leaflet bilayer of the red blood cell, as well as mild hemolysis. McLeod females have only occasional acanthocytes and very mild hemolysis; the lesser severity is thought to be due to X chromosome inactivation via the Lyon effect. Some individuals with McLeod phenotype develop myopathy, neuropathy or psychiatric symptoms, producing a syndrome that may mimic chorea.
McLeod syndrome can cause an increase in the enzymes creatine kinase (CK) and lactate dehydrogenase (LDH) found in routine blood screening.

Famous quotes containing the words disease and/or associations:
“Is not disease the rule of existence? There is not a lily pad floating on the river but has been riddled by insects. Almost every shrub and tree has its gall, oftentimes esteemed its chief ornament and hardly to be distinguished from the fruit. If misery loves company, misery has company enough. Now, at midsummer, find me a perfect leaf or fruit.”
—Henry David Thoreau (1817–1862)
“There is ... no glamor at banquets—I mean the large formal banquets of big associations and societies. There is only a kind of dignified confusion that gradually unhinges the mind.”
—James Thurber (1894–1961)
