eurons, there is sensory ataxic neuropathy.17 Immunization of rabbits with GDlb also causes sensory ataxic neuropathy mimicking the human disease.18 Of interest, the first described patient with sensory ataxic neuropathy and GDlb antibodies had also ophthalmoplegia,19 as seen in MFS and the present series.10 As COVID-19 spike interacts with the GalNAc residue of GM1 and ganglioside dimers for anchoring to cell surface gangliosides,15 cross-reactivity between epitopes within the COVID-19 spike-bearing gangliosides and signature sugar residues of surface peripheral nerve glycolipids is a very likely possibility. Such typical molecular mimicry has been shown between perip
