Penetrance In males, the penetrance of neurologic and neuromuscular manifestations of mls is high after age 50 years, perhaps even complete. available data indicate that most males with the "mcleod blood group phenotype" will develop clinical symptoms of mcleod neuroacanthocytosis syndrome [bertelson et al 1988, hardie et al 1991, danek et al 2001a, jung et al 2001b]. in a few individuals, however, neurologic and neuromuscular symptoms may be absent or only minor even after long-term follow up [jung et al 2003, walker et al 2007a]...

Summaries for Mcleod Syndrome

OMIM : 57 Hematologically, McLeod syndrome is characterized by the absence of red blood cell Kx antigen, weak expression of Kell red blood cell antigens, acanthocytosis, and compensated hemolysis. Most carriers of this McLeod blood group phenotype have acanthocytosis and elevated serum creatine kinase levels and are prone to develop a severe neurologic disorder resembling Huntington disease (143100). Onset of neurologic symptoms ranges between 25 and 60 years (mean onset 30-40 years), and penetrance appears to be high. Additional symptoms include generalized seizures, neuromuscular symptoms leading to weakness and atrophy, and cardiomyopathy mainly manifesting with atrial fibrillation, malignant arrhythmias, and dilated cardiomyopathy (summary by Jung et al., 2007). The cooccurrence of McLeod syndrome and chronic granulomatous disease (CGD; 306400) results from a contiguous gene deletion (Francke et al., 1985). (300842)

MalaCards based summary : Mcleod Syndrome, also known as mcleod neuroacanthocytosis syndrome, is related to choreoacanthocytosis and muscular dystrophy. An important gene associated with Mcleod Syndrome is XK (X-Linked Kx Blood Group), and among its related pathways/superpathways is Dilated cardiomyopathy (DCM). Affiliated tissues include brain, heart and lung, and related phenotypes are depressivity and dysarthria

Genetics Home Reference : 25 McLeod neuroacanthocytosis syndrome is primarily a neurological disorder that occurs almost exclusively in boys and men. This disorder affects movement in many parts of the body. People with McLeod neuroacanthocytosis syndrome also have abnormal star-shaped red blood cells (acanthocytosis). This condition is one of a group of disorders called neuroacanthocytoses that involve neurological problems and abnormal red blood cells.

NIH Rare Diseases : 53 McLeod neuroacanthocytosis syndrome is primarily a neurological disorder that occurs almost exclusively in males. Only about 150 cases have been reported worldwide. This condition affects movement in many parts of the body. People with this condition also have abnormal star-shaped red blood cells (acanthocytosis). This condition is one of a group of disorders called neuroacanthocytoses that involve neurological problems and abnormal red blood cells. McLeod neuroacanthocytosis syndrome is inherited in an X-linked recessive fashion and is caused by mutations in the XK gene.

UniProtKB/Swiss-Prot : 75 McLeod syndrome: A multisystem disorder characterized by the absence of red blood cell Kx antigen, weak expression of Kell red blood cell antigens, acanthocytosis, and compensated hemolysis. Most carriers of this McLeod blood group phenotype have acanthocytosis and elevated serum creatine kinase levels and are prone to develop a severe neurologic disorder resembling Huntington disease. Additional symptoms include generalized seizures, neuromuscular symptoms leading to weakness and atrophy, and cardiomyopathy mainly manifesting with atrial fibrillation, malignant arrhythmias, and dilated cardiomyopathy.
