What is a characteristic of Sudden Infant Death Syndrome?

Sudden Infant Death Syndrome (SIDS) is characterized by the unexplained death of an otherwise healthy infant, typically during sleep. One of the key factors about SIDS is that it is not primarily linked to genetic factors. Although there are some hereditary components that might predispose an infant to risk factors like respiratory conditions, the syndrome itself does not have a clear genetic basis.

Studies suggest that SIDS is more complex and multifactorial, involving environmental and developmental factors rather than being solely determined by genetics. This understanding highlights the emphasis on safe sleep practices and environmental influences, which are relevant in reducing the risk of SIDS. As a result, the assertion that SIDS is not considered to be largely hereditary is indeed a correct characterization of this phenomenon.
