PALB2 and Friedreich ataxia: PALB2 (partner and localizer of BRCA2) is the official gene symbol for FANCN. However, it should be noted that Lim et al. found individuals in the Finnish population who were homozygous for FANCM loss-of-function mutations but appeared to have no reported FA phenotype [37], casting doubt over the pathogenicity of this gene in FA.
