Differential Susceptibility to Hypertension Is Due to Selection during the Out-of-Africa Expansion

Young, J. Hunter, Chang, Yen-Pei C, Kim, James Dae-Ok, Chretien, Jean-Paul, Klag, Michael J, Levine, Michael A, ...

Hypertension is a leading cause of stroke, heart disease, and kidney failure. The genetic basis of blood pressure variation is largely unknown but is likely to involve genes that influence renal salt...

Comparative study of microsatellite and cytogenetic markers for detecting the origin of the nondisjoined chromosome 21 in Down syndrome

Petersen, Michael B., Frantzen, Merete, Antonarakis, Stylianos E., Warren, Andrew C., Van Broeckhoven, Christine, Chakravarti, Aravinda, ...

Nondisjunction in trisomy 21 has traditionally been studied by cytogenetic heteromorphisms. Those studies assumed no crossing-over on the short arm of chromosome 21. Recently, increased accuracy of...

Utility and efficiency of linked marker genes for genetic counseling. II. Identification of linkage phase by offspring phenotypes

Chakravarti, Aravinda, Nei, Masatoshi

For a linked marker locus to be useful for genetic counseling, the counselee must be heterozygous for both disease and marker loci and his or her linkage phase must be known. It is shown that when...
