C A Future Direction 5321 and Curly Calf

ALL of this analysis assumes that CCS comes directly from G A R Precision 16800...
Based on the report from Accelerated Genetics, it's almost impossible to not come to the conclusion that C A Future Direction 5321 is a carrier for curly calf syndrome. Of the seven listed bulls, three have only one connection to 1680 and it's through 5321.
The positive result of Circle S At Ease 4221 implies that Rito 1I2 of 2536 Rito 6I6 is also positive through his dam, the highly popular G A R Precision 2536 donor cow. Efficiency NFI and Three Trees Lexington T0678 imply that RITO 2V1 OF 2536 1407 is a carrier through that female as well (which the positive test result confirms). Again, that was bore out through the test results but only adds strength to the idea that 5321 is a carrier.
