Cockapoos come in a variety of sizes and can weigh anywhere from 6 to 30 pounds. The weight of a cockapoo depends on the size of its parents.
The four types of oculocutaneous albinism each result from mutations in a single gene: TYR, OCA2, TYRP1, or SLC45A2. Changes in the TYR gene cause type 1; mutations in the OCA2 gene are responsible for type 2; TYRP1 mutations cause type 3; and changes in the SLC45A2 gene result in type 4.he four types of oculocutaneous albinism each result from mutations in a single gene: TYR, OCA2, TYRP1, or SLC45A2.

Types of albinism. Types of albinism, based mainly on which mutated gene caused the disorder, include: Oculocutaneous albinism. Oculocutaneous (ok-u-low-ku-TAY-nee-us) albinism is caused by a mutation in one of four genes.People with oculocutaneous albinism (OCA) type 1 have milky white skin, white hair and blue eyes at birth. People with this disorder have signs and symptoms similar to people with oculocutaneous albinism, but they may also develop lung and bowel diseases, or a bleeding disorder. 2  Chediak-Higashi syndrome. 3  Chediak-Higashi syndrome is a rare form of albinism associated with a mutation in the LYST gene.
