Pipecolic acidemia, also called hyperpipecolic acidemia or hyperpipecolatemia,^[1] is a very rare autosomal recessive metabolic disorder that is caused by a peroxisomal defect.

Pipecolic acidemia can also be an associated component of Refsum disease with increased pipecolic acidemia (RDPA),^[2] as well as other peroxisomal disorders, including both infantile and adult Refsum disease,^[3]^[4]^[5] and Zellweger syndrome.^[6]

Characteristics

The disorder is characterized by an increase in pipecolic acid levels in the blood, leading to neuropathy and hepatomegaly.
