Certain mutagens are not teratogenic due to their localized effects and inability to impact fetal development. While all mutagens can damage DNA, not all teratogens directly mutate DNA; they can induce physiological changes leading to birth defects. For instance, UV radiation is classified as a mutagen but does not act as a teratogen because its effects are not easily transmitted to a fetus. This distinction highlights the complexity of how different agents affect development.

nucl34rgg said:I was under the impression that all mutagens were teratogenic, but not all teratogens are mutagens. Certainly, anything that can damage DNA could potentially cause birth defects. However, teratogens are more general than that and can induce physiological changes that lead to birth defects rather than mutating DNA directly.
Ryan_m_b said:I was under the impression that teratogenics are agents that end up causing severe birth defects due to developmental abnormalities. This doesn't mean they're necessarily mutagens (as far as I'm aware), just that they interfere with developmental pathways.
Ygggdrasil said:There may also be some mutagens that don't act as teratogens because their mutagenic effects are very local and may not be easily passed to a fetus. For example, UV radiation is mutagenic but not teratogenic.
True, though UV could be teratogenic it is highly unlikely (I'm struggling to think of any reasonable situation where a UV torch would get anywhere near a uterus).Ygggdrasil said:There may also be some mutagens that don't act as teratogens because their mutagenic effects are very local and may not be easily passed to a fetus.
