Which of the following conditions is primarily linked to genetic factors?

Hyperhidrosis is primarily linked to genetic factors, as it often runs in families and can be inherited. This condition is characterized by excessive sweating that occurs even in the absence of heat or physical exertion, and it may affect specific areas or the entire body. Studies have indicated that a familial tendency can contribute to the development of hyperhidrosis, indicating a significant genetic component.

In contrast, while bromidrosis (unpleasant body odor) and anhidrosis (inability to sweat) may have some underlying genetic factors, they are often more closely associated with environmental influences, lifestyle, or health conditions rather than being primarily genetic. Basal cell carcinoma, a type of skin cancer, is influenced by environmental factors such as sun exposure and is not predominantly linked to genetic inheritance. Thus, among the options provided, hyperhidrosis stands out as having a greater association with genetic predisposition.
