Remarks |
Clinically affected; diagnosed at 33 yr; deceased one week before 40th birthday; other family members with NPC; neonatal jaundice; yellow sclera for three days; MRI showed iron deposits, mild sucal widening, and bilateral frontal hyperperfusion; ataxia; vertical gaze palsy; dysarthria; dysphagia; organic affective disorder; sleep walking; moderate movement difficulty; no verbal communication; constant difficulty swallowing; fibroblasts showed 44 pmol CE/mg protein/6 hr activity in a cholesterol esterification assay [normal mean was 1855 +/- 1327 pmol CE/mg protein/6 hr, see Park et al. Hum Mut 22:313-325 (2003)]; fibroblasts were scored as npc-like in a filipin staining assay (see Park et al., 2003); a complementation test showed that the cells were type 1 (see Park et al., 2003); the donor subject is a compound heterozygote at the NPC1 gene locus: allele 1 carries a substitution (A>T) at nucleotide 2621 (c.2621A>T) in exon 18, resulting in a missense mutation at codon 874 [D874V (ASP874VAL)]; allele 2 carries a substitution (C>G) at nucleotide 2670 (c.2670C>G) in exon 18, resulting in a nonsense mutation at codon 890 [Y890X (TYR890TER)]; the subject also carries the following polymorphisms: (T>C) at nucleotide 387 (387T>C) resulting in a silent mutation (Y>Y) at codon 129 [Y129Y, (TYR129TYR)]; (C>G) at nucleotide 1926 (1926C>G) in exon 12 resulting in a missense mutation (I>M) at codon 642 [I642M (ILE642MET)]; IVS12+8(G)9-14; the first nucleotide of the initiating MET codon is numbered +1. This fibroblast is a characteristically poor grower and will only be shipped frozen; requires particular care during growth; the recommended seeding density is 15,000 to 20,000 cells per cm2. |
