- Entrez ID: 3240
- Ensembl ID: ENSG00000257017

Factors:

HP haptoglobin ( 3240 / ENSG00000257017 )

Description:

"Given the significant association of HP1/1 genotype and HP1 allele with increased life-expectancy, we also performed HP1F/S subtyping to check the possible existence for a preferential advantage of HP1F or HP1S allele... No significant differences were noticed between age groups studied either considering total HP1F and HP1S allele frequencies... or according to HP 1/2 genotypes...". The population was divided into 3 sex-specific age classes: for men [women], Age Class 1: <66 years old [<73], Age Class 2: 66–88 [73–91], Age Class 3: >88 [>91]

Ethnicity: Italian
Age of cases: >88
Finding: Negative

Statistics
- Number of cases/controls: 1072 total (initial)
- Odds ratio: 0.818
- p-value: 0.33 [0.33]
- Significant: No

Study Design
- Classifications: No Age Effect
- Study type: Candidate Region/Gene
- Technology: Biometra T-gradient thermal-cycler
