D874V; NIEMANN-PICK DISEASE, TYPE C1 |
| Identified Mutation |
ASP874VAL |
| Remarks |
Clinically affected; fibroblasts showed 48 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 an in-frame deletion (delCAT) at nucleotide 813-815 (c.813_815delCAT) in exon 6, resulting in a deletion of codon 271 [I271del (ILE271del)]; allele 2 carries a substitution (A>T) at nucleotide 2621A>T (c.2621A>T) in exon 18, resulting in a missense mutation at codon 874 [D874V (ASP874VAL)]; the first nucleotide of the initiating MET codon is numbered +1. |
