Progressive Retinaatrophie B Typ 1 (PRA-B1)Die progressive Netzhautatrophie (PRA) bei Hunden ist eine Gruppe von genetisch heterogenen erblichen Netzhauterkrankungen, die durch progressive Netzhautdegeneration und den Tod von Photorezeptorzellen gekennzeichnet sind.

Die progressive Netzhautatrophie (PRA) bei Hunden ist eine Gruppe von genetisch heterogenen erblichen Netzhauterkrankungen, die durch progressive Netzhautdegeneration und den Tod von Photorezeptorzellen gekennzeichnet sind. PRA betrifft über hundert Hunderassen. Derzeit wurden mehr als zwanzig Varianten in neunzehn Genen mit der Krankheit in Verbindung gebracht. Klinische Befunde bei PRA umfassen einen allmählichen Verlust des Sehens und eine Abschwächung der retinalen Blutgefäße, die aus der Degeneration der Photorezeptorschicht in der Netzhaut resultieren.

Bei Zwergschnauzern gibt es mehrere Formen von PRA, die sich im Alter des Auftretens und in der Geschlechtsverteilung unterscheiden (PRA B, PRA A). Bis vor kurzem wurde angenommen, dass das ursächliche Gen für PRA B PPT1 ist, jedoch betrug die Penetranz der getesteten Mutation nur 79 %, was einen großen Anteil der PRA B-Fälle unerklärt ließ. Im Jahr 2020 analysierten Kaukonen et al. PRA-betroffene Zwergschnauzer und fanden heraus, dass es 2 Typen von PRA B gibt – PRA B1, das mit dem HIVEP3-Gen assoziiert ist und die Mehrheit der Fälle erklärt, und PRA B2, das mit dem X-Chromosom assoziiert ist (zum jetzigen Zeitpunkt ist die Mutation nicht bekannt).

In unserem Labor testen wir die HIVEP3-Genmutation, die als vollständig penetrant und kongruent mit klinischen Zeichen nachgewiesen wurde. Nicht alle Fälle von PRA können durch diesen Gentest bei Zwergschnauzern erklärt werden, da mindestens eine distincte Form von PRA neben der HIVEP3-assoziierten PRA B1 in der Rasse vorhanden ist.

Vererbung: autosomal rezessiv

Mutation: HIVEP3-Gen

Gentest: Die verwendete Methode zum Testen ist äußerst genau und ermöglicht eine vollständige Differenzierung zwischen betroffenen Tieren, Trägern und gesunden Hunden. Der Test kann in jedem Alter durchgeführt werden.

A good product
Color: Black-27.5"x11.8"
Size is accurate and this is important in my situation as I use a pull out key tray and wanted edge to edge coverage. Depth is good but in my case I would have liked a deeper dimension as an option. Phone charger works well, the mouse slides smoothly

Will not charge your phone
Color: Black-Stock Market-31.5"x15.8"(with Wall Charger)
I love this mat, but it doesn't do what it says... I bought this mat for the candlesticks! The charging station was a bonus. It is very large and covers my working area, which I like. But when I go to charge my phones, it doesn't work! I placed my Android phone on the magnetic charging circle, and it showed the lightning bolt charging icon. I looked at it 5 minutes later to see how much it charged, and it was at the same % when I put it on, and the lightning bolt was gone. I tried three times, and it never charged! I then tried with my Apple phone, and the same thing, it doesn't charge. Buy this for the mat's aesthetics only; don't expect it to charge phones or earbuds...

Perfect earring tree
Color: Bronze
I was so tired of fumbling through a handful of tangled earrings in my jewelery box every morning - went looking for something to organize them and found this lovely tree. Since I am a admirer of all things bird, the design appealed to me. I was a bit worried it might be too garish, but was pleasantly surprised. The burnished copper-like finish is quite nice, and the embossed designs on the trunk and leaves give it a three-dimensional look. The nest is sturdy and holds my rings and bracelets, and I could hang necklaces from the branches (but I have another place for those.) I was worried it would be too large for my counter top - it is 17" tall x 15" wide - but it works well as a decorative piece. The sturdy base (7"x3") provides stability. Lots of holes for earrings and works just as well for dangles as for posts. All in all I am very pleased with this purchase. It came in a sturdy box and only one leaf was slightly crimped, which was easy to gently bend back into shape. And best of all - no more tangled mess of wires and hoops to sort out each morning!

Great earring tree!I
Color: Silver, Color: Silver
I like this earring tree more than I’d expected to! It holds a lot of earrings, is very sturdy and stable, and cute. It also has a little nest basket where you can put items like bracelets and rings. I love that I can see my earring options, and find the ones that best go with my outfit when getting ready for work in the morning. I’m glad it’s metal, almost a work of art, vs cheap plastic. It’s a pleasure to look at, not just functionally useful.

Exactly what I wanted!
It is really exactly what I was looking for. I've been living with my jewelry in ziplock bags since we moved over here and everything fits perfect. I saw some reviews that claimed it was unstable but I tested it and it seems sturdy though I'm not hanging heavy pieces. It is a nice size and I love the little ring basket. It also feels pretty decent quality too. Glad I got the black one as I'm not sure where I have it that the copper/bronze would look right. I think it is elegant, practical and I wish I could post a photo with my pieces on it to show that it really holds things beautifully.
