Greyhound — Hereditary nasal parakeratosis (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: Greyhound (Dog)Disorder: Hereditary nasal parakeratosisMode of inheritance: Autosomal recessiveClin feat: As summarised by Jagannathan et al. (2013), HNPK affected dogs develop crusts and fissuring of the nasal planum at a young age but are otherwise healthy. The pathognomonic histopathological changes consist of a marked diffuse parakeratotic hyperkeratosis characterized by the retention of nuclei in the stratum corneum and an accumulation of proteinaceous fluid (“serum lakes”) within the stratum corneum.Defect: yes

- OMIA molecular-genetics note: Whole-genome sequencing of one of the affected dogs by Jagannathan et al. (2013), and comparison of this sequence in the ~1.6Mb candidate region with the canine reference sequence revealed four non-synonymous variants, one of which "turned out to represent an artifact due to an error in the reference genome assembly". Genotyping of the other three variants in a large (>500) cohort of affected a…
