Decreased circulating apolipoprotein AI concentration (HP:0031799)help
Term ID: 31799
Name: Decreased circulating apolipoprotein AI concentration
Synonym: Decreased apo-AI level; Decreased apoA-I level; Decreased apolipoprotein AI level
Definition: Reduced criculating level of apolipoprotein AI, which is the major protein component of high density lipoprotein (HDL) in plasma. Defects in this gene are associated with HDL deficiencies, including Tangier disease.
