H340 Canine Brachycephaly

Background

Facial retrusion is common to brachycephalic dog breeds. A genetic study identified a quantitative trait loci (QTL) on CFA1, which considerably contributes to face length variation. Most likely causative is an intronic LINE-1 sequence within the SMOC2 gene, which reduces SMOC2 expression in brachycephalic dogs. The LINE-1 sequence was found in 91,5% of chromosomes of brachycephalic dogs but only 2,1% of chromosomes of non-brachycephalic dogs.

Test specific information

-

Age

Symptoms will develop at a young age. Within a few hours to a maximum of several weeks after birth, the characteristics that go with these genetic effects will become visible.

Turn Around Time

The turn-around-time of a test depends to a large extent on the logistics of sample transportation to the laboratory. After receiving the sample at the test location, you can normally expect the result within 10 working days. A longer delivery time applies to tests carried out by a Partner Lab.
