FXN gene methylation determines carrier status in Friedreich ataxia

Lam C, Gilliam KM, Rodden LN, Schadt KA, Lynch DR, Bidichandani S.; J Med Genet. 2023 Jan 12:jmedgenet-2022-108742. doi: 10.1136/jmg-2022-108742. Epub ahead of print. PMID: 36635061. 

 FXN DNA methylation reliably detects the GAA-TRE in the heterozygous state and offers a robust alternative strategy to diagnose FRDA due to compound heterozygosity and to identify asymptomatic heterozygous carriers of the GAA-TRE.
