Chromosomes studies in heritable thyroid diseases

ABSTRACT

The thyroid disorders studied - hyperthyrodism, endemic goiter and non-endemic or sporadic goiters- are not associated with gross chromosomal abnormalities, either morphologically or numerically. This does not exclude, however, the possibility of minute alterations in the chromosomes not discernible by the human eye. The possibility of a defect at the biochemical or molecular level in these thyroid diseases remain to be explored. (Conclusion)
