Adenosine monophosphate deaminase deficiency type 1
(重定向自Myoadenylate Deaminase Deficiency)

Adenosine monophosphate deaminase deficiency type 1, also called myoadenylate deaminase deficiency (MADD), is a recessive genetic metabolic disorder that affects approximately 1–2% of populations of European descent. It appears to be considerably rarer in Asian populations. The genetic form is caused by a defect in the gene for AMP deaminase though there is also an acquired form of AMP deficiency.
