Amino acid replacement: G?R.
The equivalent mutation to the ALS-associated G37R mutation in Hsap\SOD1 has replaced the endogenous gene at the Sod1 locus. (Note names are based on the Hsap\SOD1 amino acid numbering system.) A LoxP "scar" of 72 nt remains. (Note that this allele also contains a natural A1013C polymorphism, which leads to the N98K missense mutation, according to the human amino acid numbering system.)

G?C
G36R | Sod1-PA
Analogous mutation in human SOD1 implicated in ALS; mutation introduced into fly gene by homologous recombination; site of nucleotide substitution in fly gene specified by author. G37 in human SOD1 aligns with G36 in Drosophila ortholog Sod1.
