A mutation on an autosome causes a particular protein to be overproduced, and the excess protein accumulates in the liver and damages it. Would the resulting disorder most likely be inherited in an autosomal dominant or recessive pattern?

- Expression of the SYR gene on the Y chromosome gives rise to the male
phenotype in humans. What do you think the inheritance pattern of SYR alleles is called? - 22q11.2 deletion syndrome, also called DiGeorge syndrome, causes atypical parathyroid glands, a heart defect, and an underdeveloped thymus gland. About 85% of patients have a microdeletion of part of chromosome 22. A girl, her mother, and a maternal aunt have very mild DiGeorge syndrome. They all have a reciprocal translocation of chromosomes 22 and 2.
- How can a microdeletion and a translocation cause the same symptoms?
- Why were the people with the translocation less severely affected than the people with microdeletion?
- What other problems might arise in the family with the translocation?
