OMIA:002271-9913 : Immunodeficiency, IL17RA-related in Bos taurus (taurine cattle)
Categories: Immune system phene
Links to MONDO diseases:
Mendelian trait/disorder: yes
Mode of inheritance: Autosomal recessive
Considered a defect: yes
Key variant known: yes
Year key variant first reported: 2020
Inheritance: Häfliger et al. (2020): " Pedigree analysis indicated autosomal recessive inheritance. . . . Genotyping of the affected cattle family [with the IL17RA c.180delC variant] confirmed recessive inheritance"
Molecular basis: Häfliger et al. (2020): "Variant calling and filtering against the 1000 Bull Genomes variant catalogue resulted in the detection of a single homozygous protein-changing variant exclusively present in both sequenced genomes. This single-nucleotide deletion in exon 3 of IL17RA on bovine chromosome 5 was predicted to have a deleterious impact on the encoded protein due to a frameshift leading to a truncated gene product."
Have human generated variants been created, e.g. through genetic engineering and gene editing
Clinical features: Häfliger et al. (2020): "The two calves showed retarded growth and suffered from severe ulcerative dermatitis with hyperkeratosis, alopecia furunculosis and subcutaneous abscess formation. Blood analysis showed correspondent leukocytosis with neutrophilia whereas minerals, macro- and micronutrients were within the reference ranges. . . . This IL17RA-associated semi lethal genodermatosis, leading to psoriasis-like skin alterations and immunodeficiency resembling zinc deficiency-like syndrome in Holstein cattle, was not reported before."
Holstein (black and white) (Cattle) (VBO_0000237).

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
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.
