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.
1 Zebra mussels get their name from the striped pattern of their shells. 2  However, the pattern varies greatly to where there are no stripes, only dark or light colored shells. 3  Zebra mussels can grow to a maximum length of about 50 mm (5-10 mm in the first year) and live four to five years. As a native to Russia, zebra mussels were introduced into the Great Lakes in 1985 or 1986, when one or more transoceanic ships discharged ballast water into Lake St. Clair. 2  Being a temperate, freshwater species, the zebra mussels found the plankton-rich Lakes St. Clair and Erie to their liking.
