Gene: Slc11a1  Location: Chr1:74375195-74386062 bp, + strand  Genetic Position: Chr1, 38.54 cM
Strain of Origin:  multiple strains
Allele Type:    Not Applicable
Mutation:    Not Applicable
Mutation detailsNatural resistance to infection with diverse pathogens, including some Mycobacterium species, Salmonella typhimurium, and Leishmania donovani, is associated with a protein having glycine at amino acid position 169, within the fourth predicted transmembrane domain (G169 or Gly169). This glycine is evolutionarily conserved in rat, human, rabbit and chicken orthologous proteins. (J:4762, J:20139, J:35004)
Inheritance:    Dominant

Multiple genes may be involved in the control of mycobacterial infections in inbred mice (J:17780); the early phase of these infections is controlled in Slc11a1r strains, but later phases are not (J:28278).

The point mutation associated with the susceptible phenotype (Slc11a1s) was initially identified as Gly105Arg. In J:25627 (1995), the authors report that the full-length mRNA encodes a protein 64 amino acids longer at the N-terminus than previously reported, including two additional transmembrane domains. Therefore, the actual amino acid substitution is Gly169Arg, and the resistant allele Gly169 (or G169). The nucleotides cannot be assigned numbers because the gene contains no TATA or CAAT element and has multiple transcription initiation sites. (J:25627)

Resistant strains include 129S4/SvJae, 129X1/SvJ, A/J, AKR/J, BUB/BnJ, C3H/HeJ, C57BR/cdJ, C57L/J, C58/J, CBA/J, DBA/2J, LP/J, NOD/ShiLt, NZB/BlNJ, P/J, PL/J, RIIIS/J, RF/J, SJL/J, SWR/J, Mus spretus (Spain). (J:4762, J:20139) Some of these strains carry silent nucleotide substitutions. (J:20139)
