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.

Turba et al., 2023 report additional variants in the vicinity that can result in allele dropout in DNA tests and indicate "the need to verify the correspondence between the [Felis_catus_9.0:}g.92439157 C variant frequency and the prevalence of HCM" due to high allele frequency of the variant in Sphynx cats in their study. Seo et al. (2024) also identified this variant frequently in  Sphynx cats but reported that the variant "was not associated with the HCM diagnosis in the studied population."
Additional breeds in which the variant has been reported are based on PMID:38371598. c. coordinates were previouly listed in OMIA based on transcript ENSFCAT00000077013.1:c.7384G>C / p.(G2462R).
