FXN - frataxin Gene
Also Known as FA; X25; CyaY; FARR; FRDA
Species: Homo sapiens
About FXN
This gene has 5 transcripts (splice variants), 208 orthologues and is associated with 2 phenotypes. Ubiquitous expression in liver (RPKM 1.7), adrenal (RPKM 1.7) and 25 other tissues.
Summary
This nuclear gene encodes a mitochondrial protein which belongs to the FRATAXIN family. The protein functions in regulating mitochondrial iron transport and respiration. The expansion of intronic trinucleotide repeat GAA from 8-33 repeats to >90 repeats results in Friedreich ataxia. Alternative splicing results in multiple transcript variants.
