This paper performs a local ancestry-aware GWAS on SCD cohorts to identify novel genetic loci associated with eGFR, uncovering regions linked to inflammation, ECM integrity, and other pathways relevant to SCD nephropathy.

The paper imputes structural variants and SNVs in Samoans using a population-specific reference panel, showing improved imputation performance compared to multi-ancestry panels.

The paper evaluates polygenic score transferability for lipid traits in Samoan populations using genome-wide imputed genotypes and finds meaningful performance for LDL-C with a genome-wide PRS-CS score.

The paper constructs a Samoan-specific imputation reference panel, showing improved genotype imputation quality compared to existing panels for Samoan populations.

The paper identifies a stop-gain variant in BTNL9 associated with lower HDL-C and higher triglycerides in Polynesian populations.

The paper uses bidirectional Mendelian randomization to show LTL lengthening increases CHIP risk, while CHIP accelerates LTL shortening, with modest mediation between CHIP and CAD via LTL.

The paper examines the direct and indirect effects of rs373863828 on type 2 diabetes and fasting glucose in Polynesians, finding BMI mediates part of its effect.

The paper identifies a population-specific missense variant in CETP that lowers CETP activity and improves lipid profile, similar to loss-of-function mutations.

The paper reports whole-genome association analyses of sleep-disordered breathing traits in the NHLBI TOPMed program, identifying rare and common variant associations.

This study identifies 59 sentinel variants and two novel genes associated with telomere length using whole genome sequences from 109,122 trans-ethnic individuals.

This study conducts genome-wide association analysis in Samoans to identify genetic variants associated with fasting serum lipid levels, finding both shared and Polynesian-specific associations.

This study finds that a missense variant in CREBRF is associated with increased height in Samoan adults and children.

The paper replicates an association between the CREBRF rs373863828 minor allele and increased BMI but reduced T2D risk in New Zealand Polynesian adults, similar to findings in Samoan populations.
