Genetic Profile Summary - Key Traits and Rarity

1. Y-DNA Haplogroup: I1-Y91123
- Paternal lineage originating in ancient Northern Europe.
- Extremely rare subclade (<0.01% of global male population).
- Associated with Gothic and Scandinavian migrations.

2. mtDNA Haplogroup: HV
- Maternal lineage found widely across Europe and parts of the Middle East.
- Moderate frequency (~10-20% of European populations).
- Linked to early Neolithic expansions and some Mesolithic persistence.

3. ACTN3 Genotype: CC
- The "sprinter" gene; full expression of fast-twitch muscle fibers.
- Common in elite power athletes.
- Present in ~18% of people globally, more frequent in Europeans.

4. COMT Genotype: AG
- Intermediate dopamine metabolism (Val/Met).
- Balance between emotional sensitivity and stress resilience.
- Found in ~45-50% of global population.

5. BDNF Genotype: CT
- Affects neuroplasticity and learning.
- Associated with stronger memory formation under certain conditions.
- CT genotype present in ~35-40% of global population.

6. MTHFR Genotype: GG (C677T wild type)
- Fully functional methylation pathway.
- No elevated risk for homocysteine issues.
- GG genotype is common (~50-60% of Europeans).

7. rs9786153 Genotype: C
- Marker for Y91123 clade on the Y-chromosome.
- Unique to specific ancient Northern European paternal lines.
- Very rare — occurs in a tiny fraction of tested individuals
