Molecular basis: Hill et al. (2019): "Atlantic herring . . . colonized the brackish Baltic Sea within the last 10,000 y." Being less salty, the Baltic Sea contains more "dissolved organic matter [that] produces a red-shifted visual environment compared with marine waters." The authors "show that visual adaptation to the new light environment was achieved through a recent and rapid selective sweep on a [missense] mutation [Phe261Tyr] in the rhodopsin gene. Furthermore, this exact same amino acid change has occurred at least 20 separate times in fish species transitioning from marine to brackish or freshwater environments. This is a remarkable example of convergent evolution."
Have human generated variants been created, e.g. through genetic engineering and gene editing

WARNING! Inclusion of a variant in this table does not automatically mean that it should be used for DNA testing. Anyone contemplating the use of any of these variants for DNA testing should examine critically the relevant evidence (especially in breeds other than the breed in which the variant was first described). If it is decided to proceed, the location and orientation of the variant sequence should be checked very carefully.
Since October 2021, OMIA includes a semiautomated lift-over pipeline to facilitate updates of genomic positions to a recent reference genome position. These changes to genomic positions are not always reflected in the ‘acknowledgements’ or ‘verbal description’ fields in this table.
