OMIA:000017-9986 : Adrenal insufficiency, congenital, CYP11A1-related in Oryctolagus cuniculus (rabbit)

Categories: Reproductive system phene , Endocrine / exocrine gland phene (incl mammary gland)

Possibly relevant human trait(s) and/or gene(s)s (MIM numbers): 118485 (gene) , 613743 (trait)

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: 1993

Cross-species summary: This is a type of XY difference of sexual development (XY DSD). This disorder results from a buildup of cholesterol in the adrenal cortex, which in turn results from a deficiency of the enzyme responsible for converting cholesterol into pregnenolone. The enzyme is cytochrome P450scc or P45011A. Renamed from 'Adrenal hyperplasia, congenital' [29/09/2023]

Species-specific name: Congenital adrenal hyperplasia

Species-specific symbol: CAH; ah

History: This disorder in rabbits was first described by Fox and Crary (1978).

Molecular basis: Molecular evidence provided by Yang et al. (1993) implicates a large deletion in the gene for cholesterol side-chain cleavage enzyme (P450SCC, renamed CYP11A1). Sequencing of the normal and mutant forms should provide definitive evidence of the nature of the mutation.

Genetic engineering: Unknown
Have human generated variants been created, e.g. through genetic engineering and gene editing

Clinical features: Death within 3 days of birth; complete feminization of external genitalia of males; grossly enlarged adrenals (195 mg cf 3 mg); hypertrophied zona fasciculta cells with multiple vacuolization

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.
