Explanation: 

Detailed explanation-1: -Gene variants (also known as mutations) can have varying effects on health, depending on where they occur and whether they alter the function of essential proteins. Variant types include the following: Substitution. This type of variant replaces one DNA building block (nucleotide) with another.

Detailed explanation-2: -Types of genetic mutations include: Germline mutation: A change in a gene that occurs in a parent’s reproductive cells (egg or sperm) that affects the genetic makeup of their child (hereditary). Somatic mutation: A change in a gene that occurs after conception in the developing embryo that may become a baby.

Detailed explanation-3: -Mutations can occur during DNA replication if errors are made and not corrected in time. Mutations can also occur as the result of exposure to environmental factors such as smoking, sunlight and radiation.

Detailed explanation-4: -Mutations can be of many types, such as substitution, deletion, insertion, and translocation.
