Abstract

Autosomal-dominant polycystic kidney disease (AD-PKD) is common in Persian and Persian-related breeds, and is sporadically reported in Scottish Fold cats. A 5-year-old male Scottish Fold cat was diagnosed with polycystic kidney disease based on screening tests and abdominal ultrasonography and died 3.5 months after diagnosis. The cat had 14 kittens with three queens, including his female sibling, with an age range of 3 months to 8 years. Genetic testing to confirm the genetic transmission of AD-PKD which detects the mutated PKD1 gene was performed. Abdominal ultrasonography confirmed the presence of renal cysts. Nineteen cats were screened in the present study (13 males and 6 females), with an age range of 3 months to 8 years. The results of renal ultrasonography agreed with the genetic test results in the 19 cats in which both tests were performed and 8 cats were diagnosed as ADPKD based on these tests. AD-PKD has not been investigated in cats in South Korea. Moreover, this is the first report of AD-PKD in a family unit of Scottish Fold cats.

상염색체 우성 다낭성 신병은 페르시안과 페르시안에서 유래된 품종에서 다발하는 질환으로, 스코티쉬 폴드 고양이에서도 간혹 보고된 바가 있다. 5살령의 수컷 스코티쉬 폴드 고양이가 기본적인 혈액 검사와 복부 초음파 등을 통해 다낭성 신병으로 진단 받은 후 3.5 개월 만에 폐사하였다. 이 고양이는 동배 암컷 고양이를 비롯한 3 마리의 암컷 고양이와 교배하여 14마리의 새끼고양이가 있었으며 연령대는 3개월령에서 8년령으로 다양하였다. 상염색체 우성 다낭성 신병인지를 확인하기 위해 변이된 PKD1 유전자에 대한 유전자 검사가 이루어졌다. 또한 복부 초음파를 통해 신장의 낭성 구조물을 확인하는 검사도 이루어졌다. 총 19마리 (수컷: 13마리, 암컷: 6 마리) 에 대한 검사가 이루어 졌으며 연령대는 3개월에서 8년령 사이였다. 검사 결과, 19마리 모두에서 유전자 검사와 초음파 검사 결과가 일치하였고, 이 중 8마리가 상염색체 우성 다낭성 신병으로 진단되었다. 아직까지 한국에서는 고양이의 상염색체 우성 다낭성 신병은 보고 된바 없으며, 본 조사는 가족 단위의 스코티쉬 폴드 고양이에 발생한 상염색체 우성 다낭성 신병에 대한 첫 보고이다.
