OMIA 000256-9685 : Cystinuria, type I - A in Felis catus

In other species: dog

Possibly relevant human trait(s) and/or gene(s) (MIM number): 220100

Mendelian trait/disorder: yes

Mode of inheritance: Autosomal Recessive

Considered a defect: yes

Key variant known: yes

Year key variant first reported: 2014

Cross-species summary: The name of this entry has been changed from type A to follow the new expanded classification system for 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".

Molecular basis: Mizukami et al. (2014): a "missense mutation (c.1342C>T) ... [resulting] in a deleterious amino acid substitution (p.Arg448Trp) of a highly conserved arginine residue in the rBAT protein encoded by the SLC3A1 gene".

Breed: Domestic shorthair.

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.
