[QUOTE="wildcatkit52, post: 1398473, member: 18755"] Myostatin, as part of the Igenity Profile, analyzes for nine different variants of the myostatin gene, even though some may not be found in all breeds. Six variants are classified as “disruptive;” these cause muscle hypertrophy (double-muscling), larger birth weights, increased dystocia and enhanced tenderness. Three myostatin variants are referred to as “missense,” and will increase muscularity and reduce external and intramuscular fat, with no change in birth weight. For all myostatin variants one copy is intermediate. Disruptive variants are: C313Y nt419 E226X nt821 E291X Q204x Missence variants are: D182N F94L S105C Piedmontese are C313Y and Disruptive variant according to Igenity. I'd like to see more studies on these in the near future. Digging through piles of misinformation on ANY and ALL breeds is sometimes tiresome. [/QUOTE]
