    Hyccin, the molecule mutated in the leukodystrophy hypomyelination and congenital cataract (HCC), is a neuronal protein. by Elisabetta Gazzerro, Simona Baldassari, Caterina Giacomini, Veronica Musante, Floriana Fruscione, Veronica La Padula, Roberta Biancheri, Sonia Scarfì, Valeria Prada, Federica Sotgia, Ian D Duncan, Federico Zara, Hauke B Werner, Michael P Lisanti, Lucilla Nobbio, Anna Corradi, Carlo Minetti

    Published 2012-01-01
    “…Intriguingly, the abundance of the molecule was upregulated at postnatal days 10 and 15, in the initial steps of myelinogenesis and then declined at 30 days when the process is complete. As Hyccin is primarily expressed in neurons and its mutation leads to hypomyelination in human patients, we suggest that the protein is involved in neuron-to-glia signalling to initiate or maintain myelination.…”
