OMIA:002608-9615 : Modifier of copper toxicosis, ATP7A-related in Canis lupus familiaris (dog) |
Categories: Homeostasis / metabolism phene
Links to possible relevant human trait(s) and/or gene(s) in OMIM: 300011 (gene)
Mendelian trait/disorder: yes
Mode of inheritance: X-linked
Disease-related: no
Key variant known: yes
Year key variant first reported: 2016
Cross-species summary: Excessive copper deposition in the body due to variants in the ATP7B gene has been named Wilson disease (see OMIA:001071 : Wilson disease). Genetic modifiers have been reported to partly protect against copper accumulation in animals with Wilson disease.
Mapping: Guevara-Fujita et al (1996) mapped the canine ATP7A gene to the X chromosome.
Molecular basis: Fieten et al. (2016): "the amino acid substitution ATP7A:p.Thr327Ile partly protected against copper accumulation" Haywood et al. (2023) “Liver and DNA samples from 24 COMMD1 affected and 10 unaffected Bedlingtons were assessed for copper and genetic variants.” The authors tested for variants in COMMD1 (OMIA variant ID:643), ATP7B (OMIA variant ID:106), ATP7A (OMIA variant ID:107) and 2 SNPs in ABCA12 (Haywood et al., 2016). "All dogs only carried the ATP7A:c.980C allele and were therefore negative for the protective mutation."
Breed:
Labrador Retriever (Dog) (VBO_0200800).
Breeds in which the phene has been documented. (If a likely causal variant has been documented for the phene, see the variant table breeds in which the variant has been reported).

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.
