Species-specific name: Yellowbelly series
Species-specific description: Dao et al. (2023) report that several color phenotypes in pet [ball pythons] animals are associated with putative loss-of-function variants in the gene encoding endothelin receptor EDNRB1: (1) frameshift variants in EDNRB1 are associated with conversion of the normal mottled color pattern to skin that is almost fully white, (2) missense variants affecting conserved sites of the EDNRB1 protein are associated with dorsal, longitudinal stripes, and (3) substitutions at EDNRB1 splice donors are associated with subtle changes in patterning compared to wildtype." The G3 Journal issued an expression of concern [PMID: 37611078] after Dao et al. "alerted the Editorial Office to the use of erroneous gene names for endothelin receptor genes. The correct annotation for the gene associated with color phenotypes (accession OP589186) is EDNRB2, and the correct annotation for the gene not associated with color phenotypes (accession OQ412607) is EDNRB1." Information in OMIA has been changed accordingly to reflect that the reported variants are in the EDNRB2 gene [25/08/2023].

Variants
By default, variants are sorted chronologically by year of publication, to provide a historical perspective.
Readers can re-sort on any column by clicking on the column header. Click it again to sort in a descending
order. To create a multiple-field sort, hold down Shift while clicking on the second, third etc relevant column
headers.
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.
