Situs inversus
Situs inversus is a congenital condition in which the major visceral organs are reversed or mirrored from their normal positions. The normal arrangement of internal organs is known as situs solitus. Many people with situs inversus have no medical symptoms resulting from the condition, although cardiac problems are the most common complication. Until the advent of modern medicine, it was usually undiagnosed.

laterality
thumb|Left hemisphere of a human brain The term laterality refers to asymmetric preference, usage, skill, or specialization of symmetric body parts in an organism. Humans exhibit laterality in many ways, including limb dominance such as left and right handedness and footedness as well as specialization of one brain hemisphere over the other for certain functions such as language. Many other animals have also been shown to exhibit laterality in their own ways.

yips
The yips are a sudden and unexplained loss of ability to execute certain skills in experienced performers such as athletes. Symptoms of the yips are losing fine motor skills and psychological issues that impact the muscle memory and decision-making, leaving them unable to perform basic skills.

LRRTM1
LRRTM1 is a brain-expressed imprinted gene that encodes a leucine-rich repeat transmembrane protein that interacts with neurexins and neuroligins to modulate synaptic cell adhesion in neurons. As the name implies, its protein product is a transmembrane protein that contains many leucine rich repeats. It is expressed during the development of specific forebrain structures and shows a variable pattern of maternal downregulation (genomic imprinting).
