| molecularNote | A T to C transition in codon 919, the equivalent codon to human 918, resulted in a protein which encoded threonine instead of methionine at this position (M919T). Silent mutations in codons 920 and 921 abolished a MunI endonuclease site. A loxP flanked neomycin cassette was inserted into an adjacent intron. |
