OMIA:000783-9615 : Pelger-Huet anomaly in Canis lupus familiaris

In other species: domestic cat , rabbit

Categories: Haematopoietic system phene

Possibly relevant human trait(s) and/or gene(s) (MIM number): 169400 (trait)

Links to MONDO diseases: No links.

Mendelian trait/disorder: unknown

Mode of inheritance: Autosomal incomplete dominant

Considered a defect: yes

Species-specific symbol: PHA

Inheritance: The inheritance is autosomal semi-dominant with incomplete penetrance (Latimer et al. 2000).

Clinical features: In heterozygous individuals, PHA is a leucocyte development-disorder, in which granulocytes and monocytes show hyposegmentation of the nuclei with a mature, coarse chromatin pattern (Latimer et al. 2000). Those changes are without any clinical relevance, but frequently lead to misdiagnosis as marked left shift, which is normally caused by inflammation, preleucaemic syndrome or drug induced changes in leucocyte morphology. It was speculated that homozygosity for the PHA allele in dogs might have a lethal effect, possibly in utero during development (Latimer et al. 2000).

Breeds: American English Coonhound, Australian Cattle Dog, Australian Shepherd, Border Collie, Boston Terrier, Cocker Spaniel, Danish/swedish Farm Dog (Dog) (VBO_0000663), Foxhound, German Shepherd Dog, Mixed breed (dog), Samoyed.
