OMIA 001661-9685 : Adrenal hyperplasia, congenital, due to 11-beta hydroxylase deficiency in Felis catus

Possibly relevant human trait(s) and/or gene(s) (MIM number): 202010

Mendelian trait/disorder: yes

Mode of inheritance: Autosomal Recessive

Considered a defect: yes

Key variant known: yes

Year key variant first reported: 2012

Species-specific name: Congenital adrenal hypoplasia (CAH)

Species-specific symbol: CAH

Inheritance: Knighton (2004) reported a single cat with deficiency of 11-beta hydroxylase. Since the deficiency is due to a mutation in the gene that encodes this enzyme (see below), the disorder is almost certainly autosomal recessive.

Molecular basis: Adopting the comparative candidate-gene strategy (based on the similarity of diagnostic signs of a single affected cat with the homologous human disorder), Owens et al. (2012) sequenced the feline CYP11B1 gene (encoding 11β-hydroxylase) in that single affected cat and a healthy control cat, identifying the causal mutation as a G>A missense SNP in exon 7 "that results in an arginine to glutamine amino acid substitution; this latter mutation results in 11β-hydroxylase deficiency-associated CAH in people".

Breed: Domestic Shorthair.

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.
