Preferred Label : Myelopathy, htlv-1-associated;
Symbol : HAM;
CISMeF acronym : HAM;
Type : Other, mainly phenotypes with suspected mendelian basis;
Alternative titles and symbols : Familial spastic paraparesis, htlv-1-associated;
Description : A tropical spastic paraparesis associated with antibody titers to human T-lymphotropic
virus type 1 in the serum was described in Martinique (Gessain et al., 1985) and in
Jamaica and Colombia (Rodgers-Johnson et al., 1985); a similar disorder, termed HTLV-1-associated
myelopathy, has been found in parts of southwestern Japan, where adult T-cell leukemia/lymphoma
(ATLL) is endemic. Osame et al. (1986) first suggested the entity of HTLV-1-associated
myelopathy. Miyai et al. (1987) described 2 families with multiple cases of HTLV-1-associated
myelopathy. Even though ATLL and HAM were observed in the same area of Japan, there
were no observations of the disorders in the same family. It is not known whether
the virus that causes ATLL is the same as that associated with HAM, although they
seem to be morphologically and immunologically similar. It is possible that they are
identical and that;
