Article Synopsis
  • Polycystic kidney disease (PKD) is a hereditary condition commonly found in cats, mainly affecting Persian and similar breeds, and has now been identified in Canadian Sphynx cats.
  • A study examined fourteen cats from two related families, and ultrasounds revealed kidney cysts in both adult tomcats and five of their kittens, with cyst counts varying from one to six per kidney.
  • Genetic testing confirmed the presence of a specific mutation in the PKD1 gene, linking the occurrence of cysts to the heterozygous status of those cats with the identified variant.

A 1-year-old European shorthair male cat with a normally developed penis was subjected to genetic, endocrinological and histological studies due to unilateral cryptorchidism. The blood testosterone level was typical for males, while the level of anti-Mullerian hormone (AMH) was very low. Surgical removal of internal reproductive organs was followed by a histological study, which revealed inactive testicles with neoplastic changes and derivatives of Mullerian ducts.

Cryptorchidism is the most common form of disorder of sex development in male dogs, but its hereditary predisposition is poorly elucidated. The gonadal transcriptome of nine unilaterally cryptorchid dogs and seven control dogs was analyzed using RNA-seq. Comparison between the scrotal and inguinal gonads of unilateral cryptorchid dogs revealed 8,028 differentially expressed genes (DEGs) (3,377 up-regulated and 4,651 down-regulated).

Umbilical hernia (UH) and inguinal hernia (IH) are among the most common defects in pigs, affecting their welfare and resulting in economic losses. In this study, we aimed to verify the association of previously reported differences in transcript levels of the , , , and genes with the occurrence of UH and IH. We examined mRNA levels in muscle and connective tissue from 68 animals-34 affected by UH and 34 controls.

Cleft lip and palate (CLP) is a well-known congenital defect in dogs, characterized by abnormal communication between the oral and nasal cavities. Its incidence rate is high and affects all dog breeds. The etiology of CLP is thought to be multifactorial, caused by both genetic and environmental factors.
