Cardioblasts do not align properly with their ipsilateral partners in homozygous embryos and often fail to migrate far enough to reach their contralateral counterparts.
The 'fas[1]' EMS allele and the 'P{PZ}05488' insertion were previously associated with the CG17716 gene, named 'faint sausage (fas)' (Lekven et al, 1998; FBrf0103312). However, a subsequent study has shown these alleles affect a different gene 'CG6197/fand' (Sauerwald et al, 2017; FBrf0234822). As far as can be ascertained, the 'fas[TK]' allele was defined by its failure to complement fas[1], P{PZ}05488 and/or fas[2] (FBrf0103312) and so this allele has also been made an allele of CG6197/fand.
