Plain-English summary
An 18-month-old male Schnauzer was brought in for chronic respiratory infections that didn't improve with various antibiotics and steroids. The dog also experienced ongoing vomiting and diarrhea that didn't respond well to dietary changes or medications. Despite receiving supportive care, the dog's condition worsened, leading to euthanasia at 20 months due to persistent respiratory and gastrointestinal issues. Genetic testing revealed a mutation in the NAT10 gene, which is linked to ciliary development and may explain the dog's health problems. This case highlights a potential new genetic cause for chronic respiratory infections in dogs.

Abstract
An 18-month-old intact male Schnauzer dog was evaluated for chronic, lifelong respiratory tract infections that were unresponsive to administration of a variety of antibiotics and corticosteroids. The dog developed persistent vomiting and diarrhea around 1 year of age that was minimally responsive to diet change, antibiotics, and corticosteroids. Despite supportive care, the dog was ultimately euthanized at 20 months of age due to persistent respiratory and gastrointestinal disease. Whole genome sequencing discovered a deleterious missense A/C mutation within the NAT10 gene, a gene essential for microtubule acetylation, appropriate ciliary development, and cytokinesis. Pipeline analysis of the genomes of 579 dogs from 55 breeds did not detect this mutation. Though never described in veterinary medicine, NAT10 mutation occurs in humans with ciliary aplasia, suggesting a pathophysiological mechanism for this dog and highlighting an associated mutation or possible novel genetic cause of chronic respiratory infections in dogs.
