Domestic Longhair — Leukocyte adhesion deficiency, type I (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: Domestic Longhair (Cat)Disorder:Mode of inheritance: Autosomal recessiveClin feat: Bauer et al. (2017): Feline LAD exhibits features similar to LAD in other species. However, clinical episodes in FLAD appeared milder allowing for an extended life expectancy under long-term antimicrobial therapy, possibly due to an alternative, CD18-independent T-cell proliferation pathway.Defect: yes
