Transgenic Allele Detail
Nomenclature
Symbol: Invsinv
Name: inversin; inversion of embryonic turning
MGI ID: MGI:1856915
Synonyms: inv, inv-
Gene: Invs  Location: Chr4:48279760-48431954 bp, + strand  Genetic Position: Chr4, 26.11 cM, cytoband B
Transgene
origin
Strain of Origin:  FVB/N
Transgene
description
Transgene Type:    Transgenic
Mutations:    Duplication, Insertion, Intragenic deletion
 
Mutation detailsThe inv mutation was caused by a transgene insertion mutagenic event that resulted in a small duplication and a 47-kb deletion. This deletion eliminated exons 3-11, causing a frameshift in the remaining coding segment. (J:50117, J:81042)
Inheritance:    Recessive

Notes
This is the only situs inversus mutation in which the asymmetries occur 100% of the time. Transgenic complementation studies demonstrated that the Invs gene alone corrects the inv mutation, and should be considered the gene responsible for the inv phenotype (J:49759, J:50117).
