| Remarks |
Clinically affected; fibroblasts showed 103 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 (G>T) at nucleotide 743 (c.743G>T) in exon 6, resulting in a missense mutation at codon 248 [G248V (GLY248VAL)]; allele 2 carries a substitution (T>C) at nucleotide 3425 (c.3425T>C) in exon 22, resulting in a missense mutation at codon 1142 [M1142T (MET1142THR)]; the subject also carries the following polymorphisms: homozygous substitution (A>G) at nucleotide 644 (644A>G) resulting in a missense mutation (H>R) at codon 215 [H215R (HIS215ARG)], homozygous substitution (A>G) at nucleotide 2572 (2572A>G) resulting in a missense mutation (I>V) at codon 858 [I858V (ILE858VAL)], IVS12+8(G)9-14; the first nucleotide of the initiating MET codon is numbered +1. |
