Homoplasmy = pure mutant mtDNAs.
Heteroplasmy = mixture of mutant and normal mtDNAs.
nd = not determined.
"Reported" status indicates that one or more publications have considered the mutation as possibly pathologic. This is not an assignment of pathogenicity by MITOMAP but is a report of literature. Previously, mutations with this status were termed "Prov" (provisional).
"Cfrm"(confirmed) status indicates that at least two or more independent laboratories have published reports on the pathogenicity of a specific mutation. These mutations are generally accepted by the mitochondrial research community as being pathogenic. A status of "Cfrm" is not an assignment of pathogenicity by MITOMAP but is a report of published literature. Researchers and clinicians are cautioned that additional data and/or analysis may still be necessary to confirm the pathological significance of some of these mutations.
"P.M." (point mutation/polymorphism) status indicates that some published reports have determined the mutation to be a non-pathogenic polymorphism.
