1 TTN was the only gene with inplicated rare variants that occurred in multiple DCM families and A region (chr9q21.11-q22.31) with no known DCM genes with a maximum heterogeneity logarithm of odds score of 1.74. Heterozygous TTN truncating mutations may not manifest unless associated with a second mutation in novel forms of core myopathy with heart disease. 2  Mutations in titin were found to cause familial restrictive cardiomyopathy.
SIZE: Zebras reach six to eight-and-a-half feet in length. Their tails are an additional one-and-a-half feet long. Zebras weigh between 530 and 820 pounds. They are four to five feet tall at the shoulder. Equus zebra is generally larger than Equus zebra hartmannae. POPULATION: Equus zebra: 600-700 in the wild.
Female zebras carry their young for a gestation period of 12 to 14 months. Baby zebras are called foals. When they are born, foals weigh around 55 to 88 pounds (25 to 40 kg), according to the San Diego Zoo. Soon after birth, foals are able to stand up and walk.
