Patient's question:
The wife's brother suffers from albinism, while the wife, father, mother, and sister are normal.Doctor's answer:
Albinism is an autosomal recessive genetic disorder. "Her brother has albinism, while her husband, father, and sister are normal." Based on their manifestations, you don't need to worry too much.Guidance:
Albinism only manifests when an individual is a homozygote (aa). If no one in your family has albinism, and assuming the albinism gene is represented as 'a', then your chromosomes are AA, and your wife's chromosomes are either AA or Aa. If you have children together, it is impossible for them to be aa (manifesting albinism). The only possible genotypes are AA or Aa, both of which result in normal manifestations.
