Why it matters

A collection of SNP markers can support repeated comparisons even when it is not a whole-genome sequence.

One marker and a profile are different units

A single marker and a collection of markers should not be treated as equivalent exposures. A profile can support comparisons that an isolated observation cannot. The significance depends on which information is present and how it can be linked to other records.

For a case assessment, identify whether the source describes individual marker results, a genotype file, or a derived report. Do not turn the mention of SNP data into an unsupported claim about whole-genome sequencing. The distinction keeps both capability and persistence claims proportionate.
