GIPC1 and oculopharyngodistal myopathy: Importantly, the mutations causing OPDM were recently identified as similar expansions of ∼70 to 200–300 CGG repeats located within the 5′UTR of two different genes, LRP12 and GIPC1 (Ishiura et al., 2019; Deng et al., 2020; Kumutpongpanich et al., 2021; Xi et al., 2021).
