C47F; NIEMANN-PICK DISEASE, TYPE C2 |
| Identified Mutation |
CYS47PHE |
| Remarks |
Clinically affected; the donor subject is a compound heterozygote at the NPC2 gene locus: allele 1 carries a substitution (G>T) at nucleotide 58 (c.58G>T) in exon 1, resulting in a nonsense mutation at codon 20 [E20X (GLU20TER)]; allele 2 carries a substitution (G>T) at nucleotide 140 (c.140G>T) in exon 2, resulting in a missense mutation at codon 47 [C47F (CYS47PHE)]; the first nucleotide of the initiating MET codon is numbered +1; fibroblasts showed no detectable activity in a cholesterol esterification assay; a complementation test showed that the cells were type 2 [see Park et al. Hum Mut 22:313-325 (2003)]. 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. |
