Chemically induced Allele Detail
Symbol: Npc1nmf164
Name: NPC intracellular cholesterol transporter 1; neuroscience mutagenesis facility, 164
MGI ID: MGI:2686741
Synonyms: Npc1spm-J, sphingomyelinosis Jackson
Gene: Npc1  Location: Chr18:12189692-12236400 bp, - strand  Genetic Position: Chr18, 6.15 cM
Strain of Origin:  C57BL/6J
Allele Type:    Chemically induced (ENU) (Hypomorph)
Mutation:    Single point mutation
Mutation detailsThis phenotypic mutant was identified in an ENU mutagenesis screen. A noncomplementation test with other Npc1 alleles showed that nmf164 represents an allele of Npc1. The mutation is an A to G transversion at coding nucleoide 3014 (c.3014A>G) in exon 20 of 25 exons, altering the corresponding amino acid from aspartate to glycine at codon 1005 (p.D1005G) in loop I of the protein between the eighth and ninth (of 13) transmembrane domains. Western blot analysis reveals that protein levels reduced to 10-15% of wild type. (J:179744)
Inheritance:    Recessive
