As with brachyury (T) mutants, heterozygotes have short tails. The tail is usually half the normal length, but can be shorter, and tail kinks also occur in some mutants.
The brachyury-like 5 mutation arose spontaneously in the C57BL/6J inbred strain at The Jackson Laboratory in 2012 and was maintained coisogenic on this background. In 2014 sperm was cryopreserved from heterozygous males.
|Allele Name||brachyury-like 5|
|Gene Symbol and Name||Tl5, brachyury-like 5|
|Strain of Origin||C57BL/6J|
|Molecular Note||This spontaneous, dominant mutation mapped to the same region of Chromosome 17 as brachyury and has the same phenotype, but has not been sequenced|
