PRA4 Genetic Tests: The Eye-Opening Truth for Lhasa Apsos
Ever heard of PRA4? No, it’s not the latest sci-fi movie or a new video game. It’s a genetic test for a variant of Progressive Retinal Atrophy (PRA) that affects our beloved Lhasa Apsos. Let’s dive into this eye-opening topic with a sprinkle of humor!

PRA, or Progressive Retinal Atrophy, sounds like something straight out of a medical drama. It’s a group of diseases that slowly destroy the light-sensing cells in the eye. Think of it as the ultimate villain in the world of canine vision. One of its sneaky variants, PRA4, likes to make a late entrance, usually showing up when a Lhasa Apso is between 5 and 9 years old. Talk about fashionably late!
But fear not, dear dog lovers! As of 2017, science has given us a superhero in the form of a DNA test for the PRA4 gene mutation. This test can classify your Lhasa Apso into one of three categories:
Healthy Hero: Your Lhasa Apso has a healthy allele from both parents. No villainous PRA4 here!
Cautious Carrier: Your Lhasa Apso has one normal allele and one defective allele. They’re carrying the gene, but not affected by it. Think of them as undercover agents.
Probable Patient: Your Lhasa Apso has a defective allele from both parents. They’re likely to develop PRA4, but at least you’ll be prepared to tackle the villain head-on.
So, if you have a Lhasa Apso, consider getting them tested. It’s like giving them a pair of superhero glasses to see the world clearly. And remember, even if they end up in the “Probable Patient” category, they’ll still be the same lovable, fluffy companion you adore. Just with a bit more character and a lot more stories to tell.
