In humans, a form of the neuronal ceroid lipofuscinosis (neuronal ceroid lipofuscinosis 7, CLN7) is associated with pathogenic variants in MFSD8, which encodes an MFS transporter that moves small solutes (yet to be identified) across membranes [63, 64]. The gene discussed is MFSD8; the disease is infantile neuronal ceroid lipofuscinosis.
