Only two families reported in the literature each with a different homozygous variant. Good evidence for p.Asn478Asp (including functional). Much less available for p.Val490Leu - this variant was also identified in a second patient with an apparent additional diagnosis of NPC. Insufficient evidence for Green at this timeCreated: 15 Apr 2019, 10:06 a.m.
