Part Descriptions

LP33147-7   FXN gene
The GAA trinucleotide repeat expansion in the FXN gene causes Friedreich ataxia, a neuromuscular condition with symptoms of ataxia, impaired speech, spasticity, and gradual loss of strength and sensation in the arms and legs. Most individuals with Friedreich ataxia have the expanded GAA trinucleotide repeat in both copies of the FXN gene. The GAA segment is repeated 66 to more than 1,000 times. About 2 percent of people with this condition have an expanded GAA trinucleotide repeat in one copy of the FXN gene and another kind of mutation in the other copy of the gene. Mutations in the FXN gene disrupt production of frataxin, greatly reducing the amount of this protein in cells. Source: Genetic Home Reference, National Library of Medicine, FXN gene

LP33147-7   FXN gene
The FXN gene (frataxin) [HGNC Gene ID:3951] is located on chromosome 9q21.11. This nuclear gene encodes a mitochondrial protein which belongs to FRATAXIN family. The protein functions in regulating mitochondrial iron transport and respiration. The expansion of intronic trinucleotide repeat GAA results in Friedreich ataxia. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jun 2009] [NCBI Gene ID:2395] Source: National Center for Biotechnology Information (NCBI) Gene

Change Reason
Changed 'FRDA' in the Component to 'FXN', the current HGNC approved gene symbol.; Based on LOINC Committee review (June 2016), "targeted" was added to the Component to clarify that this test is looking for a specific set of mutations as described in the LOINC User Guide under the Molecular Genetics section.; Based on LOINC Committee review (June 2019), updated the Property from "Prid" to "Find" and Scale from "Nar" to "Doc" to align with the current LOINC model for naming collections of information reported in narrative and/or structured formats.
