| Primary Identifier | MGI:3026621 | Allele Type | Spontaneous |
| Gene | In(6)1J | Strain of Origin | C3H/HeJ |
| Is Recombinase | false | Is Wild Type | false |
| description | C3H/HeJ and C3H/HeJBir carry this inversion; C3H/HeSnJ and C3HeB/FeJ do not. Examination of recombination distances in Recombinant Inbred (RI) strain sets developed using C3H/HeJ as a progenitor suggest none of these harbor the inversion. Mouse strains carrying spontaneous mutations that arose on the C3H/HeJ background after 1965-1970 could carry the inversion and are expected to if the mutation arose after the early 1970s. |
| molecularNote | The In(6)1J inversion covers approximately 20% of Chr 6 in C3H/HeJ mice. Therefore, linkage crosses using C3H/HeJ will show no recombination in this region of Chr 6. Genetic analyses of congenic construction crosses suggested that the suppressed region lies between D6Mit124 (cytological band 6C3) and D6Mit150 (cytological band 6F1). FISH analyses using flanking BACs detected a paracentric chromosomal region between ~73 Mb and ~116 Mb. |
