OMIA 000821-9685 : Hyperoxaluria, primary, type II (Oxalosis II) in Felis catus

Possibly relevant human trait(s) and/or gene(s) (MIM number): 260000

Mendelian trait/disorder: yes

Mode of inheritance: Autosomal Recessive

Considered a defect: yes

Key variant known: yes

Year key variant first reported: 2009

Species-specific symbol: PH2

Molecular basis: By sequencing the most likely comparative candidate gene (based on clinical signs), Goldstein et al (2009) identified a causal mutation as a "point mutation, G to A, . . . at the 3# splice acceptor site of intron 4". They speculated "that the lack of the necessary terminal AG sequence of intron 4 would result in a misplicing event. This would result in the splicing out of exon 5, resulting in a shortened and abnormal mRNA and protein."

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.
