Xenopus gene changed from MGC69520 , Novel 7 transmembrane receptor (rhodopsin family) protein to gpr4l.2, G protein-coupled receptor 4 like gene 2.
This change was motivated to replace the MGC# symbol with something more meaningful, and was based on lack of synteny to true grp4 (see below) and a DIOPT/EggNog analysis, which aligned the protein to GPR4 in ~100 other species with very high confidence and similarity.
Although on the same chromosome as true gpr4 gene, these 2 genes are not adjacent to true gpr4, and therefore are not considered as gpr4 duplicates ( in which case they could be named gpr4.2 and grp4.3), but will be provisionally called 'like' genes.

Note that true orthologs of GPR4 are flanked by elm1/2 and opa3 , while these grp4-like genes are flanked by shkbp1 and sptbn4.
