Themitochondrial folate transporter (MTF) is atransport protein that facilitates the transfer oftetrahydrofolate across theinner mitochondrial membrane. It is encoded by the SLC25A32 gene and belongs to themitochondrial carrier superfamily.
The mitochondrial folate transporter was first described in 2000.[1]
Mutations of the SLC25A32 gene cause the condition putatively called "riboflavin-responsive exercise intolerance" (RREI), also known asSLC25A32 deficiency. The first case report linking this condition to SLC25A32 was published in 2016.[2] Several additional cases of SLC25A32 deficiency have been described since.[3][4] The phenotype of the patients is reminiscent ofmultiple acyl-CoA dehydrogenase deficiency (MADD).
According to a review published in 2020, mutations of the SLC25A32 gene have been shown to causeneural tube defects in mice, and they have been associated with several human cases, based on a re-sequencing of DNA of patients with neural tube defects.[5]
