This has come up on the PSSM forum. Good to see a breeder acting responsibly (I think - I'm not sure whether he is still siring foals). Its google translate at work and seems to mean the gene is semi-dominant.

Explanation for our breeders:
As you certainly know, our don martillo, world champion of young dressage horses 2017, is still not fit. He suffers from a movement disorder, described as " shaking ", with the diagnosis " shivering syndrome " now appears unlikely. However, the exact diagnosis is still not fixed. The movement disorder is expressed in a hyper (excessive lift) of the rear leg.

In the meantime, we have found a gene variant at Don Martillo, which is linked to this particular symptom. It is a semi-halberbige variant of a muscle white, which is also linked with an over-tight kidney area, a span, a tail, and a more threaded jump joint in more round leg.

Since the variant is only half large, only 50 % of its descendants should have this variant. That is why we offer a free analysis of the variant of the variant of Don Martillo. For This, there is a stage of about 30-50 feet of hair with hair roots (important! ) fitted in a plastic bag with life number of the foot and in the envelope:

Werlhof Institute
Of. HD. PD DR Med. M. V. Anxieties
Sign Street 23
30159 Hanover

After completion of the analysis, our breeders will then receive a certificate with the result. We hope to ensure greater transparency and better marketing of don martillo foals in the sense of our breeders.
 
Thanks, Shortstuff99, I'd seen those two articles, but they don't have the information that would have been present in the German text that I think would have been issued by the Werlhof Institut.

From my limited knowledge of genetics and German, I think that it is an autosomal dominant variant of a gene encoding for a muscle protein.

Yes that's what I get too, also with them stating a 50% chance of offspring having it makes me think he only has one copy of the faulty gene too (so heterozygous). And that depends on what the mare has too.
 
Don't know much about the science (or the sire for that matter) but surely there are other sires which are just as good, and aren't genetically compromised? As such, I would respectfully suggest that the breeder cease offering as a sire if they haven't already done so, and potentially this chap's offspring oughtn't to be bred either.

I'd not consider putting a mare anywhere near a bloodline where there is a known problem - it's not like there isn't enough choice out there!

that’s precisely what the article is about. Plus free testing for offspring to date.
