Analysis of the Genetic Basis of Height in Large Jewish Nuclear Families

This is a family based study of the genetic basis of height, which focused on very large nuclear families (10 siblings or more, average of 12), all from a founder (Jewish) population. All participants have completed their growth. This study design increases the frequency of some genetic variants that are rare in a cosmopolitan population but segregate in our cohort. Participants were genotyped with a ~630,000 SNP array (Affymetrix Axiom Biobank), and their standing height, sitting height and arm span were measured with high accuracy (±0.1 cm, with 4 technical repeats). All genomic coordinates refer to genome build hg19.
