Patterns of Inheritance: Genetic DisordersAmna Adnan
The genetic risk in these disorders is typically due to multiple genetic and genomic variants, each with a small effect size. While these conditions tend to cluster in families, the expression of disease is dependent on the interaction between genetic and environmental factors. Special considerations...
Single gene trait examples include eye color, presence of freckles or dimples, type of ear lobe, and widow's peak hairline. How are single gene disorders inherited from parents? If a genetic disorder is linked to the dominant allele, a child can inherit the disease from parents even if just...
Over the last decade there have been major advances in our understanding of the genetic basis of mitochondrial disease, enabling genetic counseling for patients with autosomal dominant and autosomal recessive disorders. Genetic counseling for patients with mitochondrial DNA (mtDNA) mutations is less well...

In humans, there are many other disorders that show multifactorial inheritance patterns, such as multiple sclerosis, diabetes, asthma,cancer, and numerousbirth defects. All of these diseases are due to a complexinteractionof genetic factors, such ascopy number variation,epistatic interactions,andmodifier...
For example, some cases of retinitis pigmentosa, a group of genetic disorders that cause progressive vision loss, are believed to be caused by digenic inheritance. In these cases, mutations in both the RP1 and RP2 genes are required to develop the condition. Similarly, some forms of hearing ...
