Cornish Rex — Vitamin D-deficiency rickets, non-type I, non-type II (hereditary; OMIA-verified breed predisposition)
Source: first-hand OMIA (University of Sydney) breed-specific hereditary-disorder record, saved verbatim to source_file; every claim below is a C1 byte-substring of it.
Claims
Breed: Cornish Rex (Cat)Disorder:Summary: This disorder is characterised by low levels of both 25-hydroxy-vitamin-D [25(HO)D] and 1,25-hydroxy-vitamin-D [1,25(HO)D], which thus distinguishes it from type I (normal 25(HO)D, low 1,25(HO)D) and type II (normal 25(HO)D, high 1,25(HO)D).Defect: yes
