OMIA 001879-9615 : Cystinuria, type II - A in Canis lupus familiaris

Possibly relevant human trait(s) and/or gene(s)s (MIM numbers): 220100 (trait) , 104614 (gene)

Mendelian trait/disorder: yes

Mode of inheritance: Autosomal Dominant

Considered a defect: yes

Key variant known: yes

Year key variant first reported: 2013

Cross-species summary: This entry has been created in line with the new expanded classification system for canine cystinuria suggested by Brons et al. (2013): "type I cystinuria when the disease shows autosomal recessive inheritance, type II when it shows autosomal dominant inheritance, and type III for sex-limited inheritance. . . . Involvement of the SLC3A1 gene is indicated by adding A, and similarly B indicates mutations in SLC7A9".

Inheritance: Brons et al. (2013) provided evidence consistent with autosomal dominant inheritance.

Molecular basis: Using the direct candidate gene strategy, based on clinical signs, Brons et al. (2013) identified "in-frame 6 bp deletion removing 2 of the 3 adjacent threonine residues in exon 6 of the SLC3A1 gene" (c.1095_1100del; p.Thr366_Thr367del) as causal in Australian Cattle Dogs.

Clinical features: As summarised by Brons et al. (2013), cystinuria type II - A is characterised by: present in males and females; not androgen-dependent; COLA [μmol/g creatinine (normal ≤500)] ≥8,000 in homozygotes and ≥3,000 in heterozygotes.

Breed: Australian Cattle Dog.

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.
