UNLABELLED: Fifteen known type 2 diabetes (T2D) gene variants were assessed for their associations with T2D status in 228 T2D families from the Framingham Heart Study (FHS) Original, Offspring, and Children Cohorts. Bayesian approach was used to test single-single-nucleotide...

BMC Proc. 2018 Sep 17;12:37. doi: 10.1186/s12919-018-0140-y. eCollection 2018.

To examine whether single-nucleotide polymorphism (SNP) by methylation interactions can be detected, we analyzed GAW20 simulated triglycerides at visits 3 and 4 against baseline (visits 1 and 2) under 4 general linear models and 2 tree-based models in 200...

Genetic analysis of long-lived families reveals novel variants influencing high density-lipoprotein cholesterol.

Frontiers in genetics

Feitosa MF, Wojczynski MK, Straka R, Kammerer CM, Lee JH, Kraja AT, Christensen K, Newman AB, Province MA, Borecki IB.
PMID: 24917880
Front Genet. 2014 Jun 03;5:159. doi: 10.3389/fgene.2014.00159. eCollection 2014.

The plasma levels of high-density lipoprotein cholesterol (HDL) have an inverse relationship to the risks of atherosclerosis and cardiovascular disease (CVD), and have also been associated with longevity. We sought to identify novel loci for HDL that could potentially...

Genome wide association and linkage analyses identified three loci-4q25, 17q23.2, and 10q11.21-associated with variation in leukocyte telomere length: the Long Life Family Study.

Frontiers in genetics

Lee JH, Cheng R, Honig LS, Feitosa M, Kammerer CM, Kang MS, Schupf N, Lin SJ, Sanders JL, Bae H, Druley T, Perls T, Christensen K, Province M, Mayeux R.

Front Genet. 2014 Jan 17;4:310. doi: 10.3389/fgene.2013.00310. eCollection 2013.

Leukocyte telomere length is believed to measure cellular aging in humans, and short leukocyte telomere length is associated with increased risks of late onset diseases, including cardiovascular disease, dementia, etc. Many studies have shown that leukocyte telomere length is...

Heterogeneity of the Predictive Polygenic Risk Scores for Coronary Heart Disease Age-at-Onset in Three Different Coronary Heart Disease Family-Based Ascertainments.

Circulation. Genomic and precision medicine

Feitosa MF, Kuipers AL, Wojczynski MK, Wang L, Barinas-Mitchell E, Kulminski AM, Thyagarajan B, Lee JH, Perls T, Christensen K, Newman AB, Zmuda JM, Province MA.

Circ Genom Precis Med. 2021 Jun;14(3):e003201. doi: 10.1161/CIRCGEN.120.003201. Epub 2021 Apr 12.

BACKGROUND: Polygenic risk scores (PRS) for coronary heart disease (CHD) may contribute to assess the overall risk of CHD. We evaluated how PRS may influence CHD risk when the distribution of age-at-onset, sex, and family health history differ significantly.METHODS:...

Identification of a Novel Locus for Gait Speed Decline With Aging: The Long Life Family Study.

The journals of gerontology. Series A, Biological sciences and medical sciences

Santanasto AJ, Wojczynski MK, Cvejkus RK, Lin S, Wang L, Thyagarajan B, Christensen K, Schupf N, Feitosa MF, An P, Zmuda JM.

J Gerontol A Biol Sci Med Sci. 2021 Sep 13;76(10):e307-e313. doi: 10.1093/gerona/glab177.

BACKGROUND: Gait speed is a powerful indicator of health with aging. Potential genetic contributions to gait speed and its decline with aging are not well defined. We determined the heritability of and potential genetic regions underlying change in gait...

Families Enriched for Exceptional Longevity also have Increased Health-Span: Findings from the Long Life Family Study.

Frontiers in public health

Sebastiani P, Sun FX, Andersen SL, Lee JH, Wojczynski MK, Sanders JL, Yashin A, Newman AB, Perls TT.

Front Public Health. 2013 Sep 30;1:38. doi: 10.3389/fpubh.2013.00038. eCollection 2013.

Hypothesizing that members of families enriched for longevity delay morbidity compared to population controls and approximate the health-span of centenarians, we compared the health-spans of older generation subjects of the Long Life Family Study (LLFS) to controls without family...

Evaluation of the Bidirectional Relations of Perceived Physical Fatigability and Physical Activity on Slower Gait Speed.

The journals of gerontology. Series A, Biological sciences and medical sciences

Qiao YS, Gmelin T, Renner SW, Boudreau RM, Martin S, Wojczynski MK, Christensen K, Andersen SL, Cosentino S, Santanasto AJ, Glynn NW.
PMID: 33170216
J Gerontol A Biol Sci Med Sci. 2021 Sep 13;76(10):e237-e244. doi: 10.1093/gerona/glaa281.

BACKGROUND: Lower physical activity levels and greater fatigability contribute independently to slower gait speed in older adults. To fully understand the bidirectional relations between physical activity and fatigability, and to inform potential intervention strategies, we examined whether physical activity...
