The application of molecular genetics to the study of mental disorders has begun in earnest. Most of the initial interest has focused on the functional psychoses as these common and debilitating disorders have long been known to have a significant genetic component. A number of groups have now reported data from RFLP linkage studies of both schizophrenia and bipolar affective disorder (manic-depression). Unfortunately the results are already conflicting with early findings of linkage unconfirmed by subsequent studies.

UI	MeSH Term	Description	Entries
D008040	Genetic Linkage	The co-inheritance of two or more non-allelic GENES due to their being located more or less closely on the same CHROMOSOME.	Genetic Linkage Analysis,Linkage, Genetic,Analyses, Genetic Linkage,Analysis, Genetic Linkage,Genetic Linkage Analyses,Linkage Analyses, Genetic,Linkage Analysis, Genetic
D012150	Polymorphism, Restriction Fragment Length	Variation occurring within a species in the presence or length of DNA fragment generated by a specific endonuclease at a specific site in the genome. Such variations are generated by mutations that create or abolish recognition sites for these enzymes or change the length of the fragment.

D002880	Chromosomes, Human, Pair 11	A specific pair of GROUP C CHROMOSOMES of the human chromosome classification.	Chromosome 11
D002895	Chromosomes, Human, Pair 5	One of the two pairs of human chromosomes in the group B class (CHROMOSOMES, HUMAN, 4-5).	Chromosome 5
