Found in 73% of hypertensive and 36% of normotensive blacks, it is generally considered a hallmark of hypertension in blacks. The higher prevalence of salt sensitivity in blacks compared with whites suggests a genetic influence on this trait, but there is little direct evidence of heritability. We determined the extent to which salt sensitivity is correlated in black families and estimated the heritability of this phenotype. Black families were recruited through a hypertensive proband. Both hypertensive and normotensive adults were phenotyped with respect to salt sensitivity with an intravenous sodium-loading, furosemide volume-depletion protocol. Salt sensitivity was defined as the difference between sodium-loaded and volume-depleted blood pressure. We enrolled 20 families, comprising 30 parent-offspring pairs and 115 adult sibling pairs. Age-adjusted familial correlations ranged from .33 to .44, .19 to .37, and .12 to .21 for mean arterial and systolic and diastolic pressure responses to the salt sensitivity maneuver, respectively. Corresponding heritability estimates were 0.26 to 0.84, 0.26 to 0.74, and 0.004 to 0.24, respectively. These data strongly suggest a heritable component of salt sensitivity.<\/jats:p>","DOI":"10.1161\/01.hyp.28.5.854","type":"journal-article","created":{"date-parts":[[2012,6,12]],"date-time":"2012-06-12T00:53:46Z","timestamp":1339462426000},"page":"854-858","update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":101,"title":["Heritability of Salt Sensitivity in Black Americans"],"prefix":"10.1161","volume":"28","author":[{"given":"Laura P.","family":"Svetkey","sequence":"first","affiliation":[{"name":"Duke University Medical Center, Durham, NC (L.P.S.); Department of Biometry and Genetics, Louisiana State University Medical Center, New Orleans (S.P.M.); and National Center for Human Genome Research, National Institutes of Health, Baltimore, Md (A.F.W.)."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sean P.","family":"McKeown","sequence":"additional","affiliation":[{"name":"Duke University Medical Center, Durham, NC (L.P.S.); Department of Biometry and Genetics, Louisiana State University Medical Center, New Orleans (S.P.M.); and National Center for Human Genome Research, National Institutes of Health, Baltimore, Md (A.F.W.)."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alexander F.","family":"Wilson","sequence":"additional","affiliation":[{"name":"Duke University Medical Center, Durham, NC (L.P.S.); Department of Biometry and Genetics, Louisiana State University Medical Center, New Orleans (S.P.M.); and National Center for Human Genome Research, National Institutes of Health, Baltimore, Md (A.F.W.)."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"e_1_3_2_1_2","doi-asserted-by":"crossref","unstructured":"Weinberger MH Miller JZ Luft FC Grim CE Fineberg NS.
