Sleepwalking may be inherited as an autosomal dominant disorder with reduced penetrance.
2.

4.
Reduced penetrance is a phenomenon where a fully inherited genetic trait, such as a disease or disorder, fails to exhibit the expected phenotype.
5.
Here, system IMINO is thought to play a role in reduced penetrance of iminoglycinuria by compensating for imino acid malabsorption related specifically to mutations of PAT2.
