Synonyms: Arx330ins(GCG7), ArxE, ArxExpanded, Arx(GCG)7, Arxtm(GCG)Kki
Gene: Arx  Location: ChrX:93286507-93298357 bp, + strand  Genetic Position: ChrX, 41.05 cM
Germline Transmission:  Earliest citation of germline transmission: J:152416
Parent Cell Line:  CCE/EK.CCE (ES Cell)
Strain of Origin:  129S/SvEv-Gpi1c
Allele Type:    Targeted (Humanized sequence)
Mutations:    Insertion, Nucleotide repeat expansion
Mutation detailsExon 2 was replaced with one in which coding nucleotide 330 (C), the third base of alanine codon 110 in the middle of the first poly-alanine stretch, was replaced with a G and had seven GCG alanine codons inserted after it (c.330C>GGCGGCGGCGGCGGCGGCGGCG). The resulting protein mutation (p.(A110_A111delinsAAAAAAAAA)) mimics a muation found in some X-linked mental retardation patients. A neomycin resistance gene cassette was inserted in to intron 1.
